▼ Alkali–silica reaction (ASR) is a major concrete durability concern that is responsible for the deterioration of concrete infrastructure in the world. The resultant of the reaction between the cement alkali hydroxides and the metastable silicates in the aggregates is a hygroscopic and expansive alkali–silicate gel (referred to as ASR gel in this document). The swelling behavior of ASR gels determines the extent of damage to concrete structures and, as such, mitigation of ASR relies on understanding these gels and finding ways to prevent them either from formation, or from swelling after formation. This dissertation focuses on the synthesis and characterization of ASR gels with wide ranges of compositions similar to what has been reported for the filed ASR gels in the literature. The experimental work consisted of three phases as follow. Phase I: Investigation of rheology, chemistry and physics of ASR gels produced through sol–method. Inspired from the existing literature, two sol–gel methods have been developed for the synthesis of ASR gels. The rheological (primarily gelation time, yield stress, and equilibrium stress), chemical (pore solution pH, pore solution composition, osmotic pressure, solid phase composition, stoichiometry of gelation reactions) and physical (evaporable water, solid content, etc.) properties of synthetic ASR gels have been extensively investigated in this phase. Ca/Si, Na/Si and K/Si, and water content were considered as the main chemical composition variables. In order to investigate the suppressing effects of lithium on the swelling properties of ASR gels, the gels were added with lithium in a part of the experimental program. The results strongly suggested that Ca/Si has a positive effect on the yield stress of the gels and their rate of gelation. Na/Si was found to have a decreasing effect on the yield stress and gelation rate (especially at low Ca/Si levels). K/Si and Li/Si had second–order (i.e., polynomial) effects on the yield stress of the gels, causing a significant drop in this parameter followed by some increase as they approached their upper values. Na/Si and K/Si were both found contribute to the osmotic potential of the ASR gels, while increase in Ca/Si generally led to a drop in this parameter. The presence of all components (Ca, Na, and K) were found to contribute to the pH of the gels’ pore solution, and Ca/Si and Na/Si showed a synergistic effect on this parameter. Lithium, on the other hand, was found to be able to drop the OH- concentration of the pore solution by a factor of five in the case of high–sodium gels, which could partially explain its ASR mitigating effect. Phase II: Investigation of the free and restrained swelling behavior, hydrophilic potential and viscoelastic properties of ASR gels produced through the “paste method”. 20 gel compositions were selected (using the central composite design method) with Ca/Si, Na/Si and K/Si molar ratios varying in the ranges (0.05–0.5), (0.1–1.0) and (0.0–0.3), respectively. The gels were produced by batching… Advisors/Committee Members: Farshad Rajabipour, Dissertation Advisor/Co-Advisor, Farshad Rajabipour, Committee Chair/Co-Chair, William D.

▼ Biomass such as spent grain is difficult to dry when it is in the slurry form. Proposed industrial solutions are to compact wet biomass first and then dry it. Compaction develops desired granular form and increases surface area for drying but also brings new technical challenges. Superheated steam (SS) drying is advantageous over hot-air drying as it is more energy efficient. A problem associated SS drying is the initial condensation leading to disintegration of biomass compacts. The current research investigates the disintegration characteristics of distiller’s spent grain (DSG) compacts while being dried in SS. The study focuses on the DSG flowability, densification characteristics and disintegration behavior of DSG compacts as affected by SS drying conditions, soluble content and particle size distribution (PSD). DSG fractions with particle sizes from 300 to 850 µm were dried in SS at 150°C and hot-air at 45 and 150°C. Under these drying conditions bulk density and angle of repose (AOR) varied from 0.379 to 0.435 g/cm3 and 46.0 to 50.4°, respectively. The stress-relaxation data obtained during the compaction of DSG at different levels of compressive pressure (60.3-135.7 MPa), initial moisture content (15, 20 and 25% wet basis- wb) and soluble content (15 and 30%) were normalized and analyzed to determine the asymptotic modulus (EA) of the compacts. The highest EA of 174 MPa was obtained for DSG compacts produced with a compressive force of 135.7 MPa, initial moisture of 25% wb and soluble content of 0%. The percentage increase in volume of DSG compacts during drying in SS at 110 to 150°C temperature range was between 78 to 130%. A comparison between the physical properties of SS dried and hot-air dried compacts revealed the role of SS in accelerating the release of mechanical energy stored in the compacts. An increase of dimensions and a considerable increase in the hardness and EA of the compacts was obtained by adding up to 70% (w/w) solubles or by decreasing the PSD of wet distiller’s spent grain from d(0.9)=1283.6 to 812.8 µm. This study establishes that compaction of wet biomass followed by SS drying can lead to its effective utilization.

▼ Standard soymilk processing uses filtration or centrifugation step to remove coarse solids in the comminuted soy. The objectives were to produce soymilk from dehulled beans by Gaulin homogenizer or produce sterile soymilk using microfluidizer-throttling or continuous flow high pressure throttling (CFHPT) to retain retaining all essential soybean solids. The soymilk was characterized for particle size distribution, rheological and ultra-structural properties, to establish an empirical model to characterize the distribution of particle size of particles in the soymilk, and to evaluate the consumer acceptability. Whole dehulled soybeans were blanched, mixed with deionized water, and comminuted coarsely in a food-processor. An intermediate comminution step in Megatron (process M) or Fitzmill (process F) or Stonemill (process S) was followed by homogenization at selected pressures using Gaulin homogenizer or microfluidizer-throttling or CFHPT system. The combined process M and CFHPT treated samples at the highest pressure showed the smallest particle size and the highest apparent viscosity. All samples showed pseudoplastic flow behavior. Ultrastructural images elucidated particle microstructure in the soymilk and homogeneity of suspended particles. The very small fat globules at highest CFHPT pressure treatment of process M were seen entrapped in the network and was uniformly distributed. Thus combined process M and the highest CFHPT pressure was considered the best treatment. Therefore, the high pressure throttling process will allow utilization of the whole soybean to produce excellent quality soymilk with high emulsion stability. The increase in the CFHPT flow rate significantly affected size reduction of particles of soymilk. The empirical models were established which can be used to predict the size of particles in soymilk, at different volume fractions, processed using high pressure throttling processes at various pressures and flow rates. Consumer acceptability test showed that more research is needed to make a soymilk that appeal to the taste of the American consumer before the CFHPT process can be used commercially to produce soymilk. Thus, soymilk with all the essential solids can be made available to the public and processors benefit from the high processing yields since none of the essential solids of the beans are discarded.

▼ There is a growing demand for innovative and affordable technologies in the food industry to modify ingredient functionality and to ensure product safety. Proteins are essential components in many food systems, and their structure can be modified in a variety of ways to control and improve functional characteristics of a food system. The enzymatic modification of proteins with transglutaminase is one such novel technology that has a broad range of applications, and was the focus of this research. In the first study of this research, hydrolyzed pea protein were modified by microbial transglutaminase (MTGase) from the Streptomyces mobaraensis species. Biologically active (biogenic) amines histamine and tyramine were used as amine donor substrates in this enzyme-catalyzed reaction. Conjugation of biogenic amines and pea protein hydrolysates was achieved in the presence of MTGase after 6 h of incubation at 37°C. Conjugation progress was monitored by high performance liquid chromatography and fluorescence spectroscopy. Seventy six percent of histamine was covalently incorporated to protein hydrolysates by MTGase, thereby reduced the concentration of undesirable biogenic amine. Also, the MTGase-catalyzed introduction of tyramine into pea protein hydrolysates substantially improved the antioxidant potential of the newly formed conjugates. In the second study, porcine skin gelatin was modified by MTGase-induced amination with tyramine in an aqueous media at 50°C. Gelation and melting iii temperatures, viscoelastic behaviour, as well as gelation rate and gel strength of tyramine-gelatin conjugates and MTGase-cross-linked gelatin were determined. MTGase-catalyzed cross-linking increased the gelation and melting temperatures of the gel. Incorporation of tyramine via MTGase did not change the gelling and melting temperatures of the gelatin. Tyramine incorporation negatively affected the gelling behaviour of the gelatin and was likely due to covalent tyramine-gelatin bonds that interfered with the normal formation of triple helix networks. Overall, this research demonstrated biogenic amines, as potential substrates for MTGase, were able to introduce into food proteins and peptides. A combination of glutamine-containing peptides together with MTGase has the potential to decontaminate fermented foods and beverages for biogenic amines.

Neste trabalho avaliou-se o comportamento reológico dos 11 molhos comerciais para salada, tratados pelo processo de irradiação por raios gama, nas doses: 3 kGy e 5 kGy. Essa avaliação foi realizada por meio de reogramas traçados por medidas de viscosidade e tensão de cisalhamento por taxa de cisalhamento. Parâmetros matemáticos, obtidos destas medidas, também contribuiram para a conclusão do comportamento apresentado e do melhor modelo matemático aplicável a cada molho. As medidas foram realizadas em um viscosímetro de Brookfield modelo LVDV III. O banho térmico Neslab foi empregado para manter a tempertura ambiente durante toda a análise. Realizou-se o protocolo de estudo em duas fases. Na fase 1, a avaliação ocorreu logo após as amostras terem sido irradiadas, as quais se encontravam próximas a suas datas de fabricação. Na fase 2 as amostras foram reavalidas após um período de armazenamento, próximo a data de expiração de suas validades. Paralelamente realizou-se medida de pH para avaliar sua estabilidade diante dos tratamentos e análises sensoriais, de dois dos onze molhos estudados, a fim de verificar a aceitação desses diante da irradiação. O comportamento pseudoplástico foi confirmado para todos os molhos através do modelo matemático, da lei da potência, que melhor se aplica a este, nas duas fases das análises. A irradiação, nas doses absorvidas estudadas, não influênciou nesse comportamento. Os resultados da análise sensorial indicaram boa aceitação dos molhos irradiados, pelos provadores.

This study evaluated the rheological behavior of 11 salad dressings ready to eat, processed by gamma irradiation, at doses: 3 kGy and 5 kGy. This assessment was made by rheograms traced by measurements of viscosity and shear stress by shear rate. Mathematical parameters obtained from these measures also contributed to the conclusion of the behavior exhibited and for choosing the best mathematical model applicable to them. The measurements were performed on a Brookfield viscometer Model LVDV - III. The Neslab thermal bath was used to maintain ambient temperature during the whole analysis. This study protocol was done in two stages. In step 1, the evaluation was performed soon after the samples have been irradiated when these were close to their dates of manufacture. In phase 2 the samples were reassessed after a period of storage, near the expiration date of their validity. Simultaneously pH measurement was performed to evaluate their stability in the face of treatment and sensory analyzes of two salad dressings were studied, in order to verify the acceptance of these when submitted to irradiation. The shear-thinning behavior was confirmed for all dressings through the mathematical model, the power law, that best model apply to this, in both phases. The irradiation at the absorbed doses studied did not influence this behavior. The results of sensory evaluation indicated good acceptance of irradiated sauces for the tasters.

▼ The viscoelastic surfactant (VES) is one of the newest chemicals that have been used as diverting agents to divert the acid to the desirable zones through directing the acid to the lowest permeability formations by building in-situ viscosity. This technique shows valuable properties in diverting and cleaning processes. However, the main problem associated with this technique is a temperature limitation; therefore, the research is continuing developing new chemicals that overcome the high-temperature short come. This study aims to evaluate the rheological properties of five new types of the VES that are proposed to be used in oil industry through conducting the lab tests on this new generation of the VES. The spent acid system which contains 6 vol% VES was prepared and the PH was adjusted between 4 and 5 while the pressure was maintained at 400 psi. The different types showed various performances in different conditions, VES001 showed high viscosity around 100 cp at a shear rate of 10 s-1 and temperature of 2000F. while VES002 didn’t show any viscosity building in high temperatures (200 and 2500F). VES003 and VES004 showed a high viscosity building around120 cp in temperature of 2500F at a shear rate of 10 s-1. Type 5 showed promising properties in high temperatures since it showed viscosity of 120 and 220 cp in 200 and 2500F, respectively. Moreover, its viscosity didn’t peak even at 3700F when it showed viscosity of 550 Cp at a shear rate of 87s-1. Further tests were obtained on the VES005 to deeply evaluate both its capability as diverting agent and its compatibility with the other acid additives. The effects of several corrosion inhibitors on the performance of the VES were studied then the optimal inhibitor was used for the further studies. Core-flood tests were conducted to emulate the performance of the system inside the formations. Two types of Indiana limestone cores, 150 mD and 12 mD, were used. The exciting diverting performance was observed through the low permeability core; however, some diverting performances were observed in the high permeability core. CT scan was used to reinforce these results. Advisors/Committee Members: Nasr-El-Din, Hisham (advisor), Holditch, Stephen (committee member), El-Halwagi, Mahmoud (committee member).

▼ In situ gelled acids that are based on polymers have been used in the field for several years as an acid diversion agent. These acids should not cause permanent formation damage, and should clean-up rapidly and completely when the well is put back on production. However, recent lab studies indicated that a significant amount of gel was retained inside the core even when the recommended breaker concentration was used. This gel significantly reduced the core permeability. Therefore, the objective of this study is to examine the working mechanisms of the solid breaker and the factors that affect the breaking time. The flowback of the spent acid and the core damage induced by it will also be assessed in detail. Viscosity and rheological experimental studies were conducted using polymer-based in situ gelled acids that used Zr as a crosslinker agent. To form the gel, this acid was neutralized using Pink Desert limestone to pH 3.5-4.The rheological properties of the gel were measured under different breaking conditions for 2 hr using HPHT rotational and oscillatory rheometers. Temperature (150 to 250 degrees F), shear rate (0.1 to 1000 s^-1), and breaker concentrations (0 to 32 lb/Mgal) were the main parameters that were investigated in this study. Experimental results showed that there is no need to add more than 16-ppg breaker concentration at 150 degrees F, while 4-ppg breaker concentration is enough at temperatures higher than 200 degrees F. A full breaking of these acids was obtained when the values of elastic modulus (G') were equalized with the viscose modules (G"). An HPHT filter press was used to simulate the flowback of the spent acid. Viscosity measurements of filtered fluids were used to determine the degree of gel degradation. Carbonate cores that had a 2.5 in. diameter and 0.25 in.thickness were used. Temperature (75 to 250 degrees F) and breaker concentrations (0 to 16 lb/Mgal) were the main parameters that were investigated in this study. Experimental results showed that there was always a gel left inside the rock, and such caused permeability reduction. Time needed to flowback the solution decreased by 50% when the temperature was increased from 150 to 200 degrees F, while it decreased by only 30% when the breaker concentration was doubled. At 150 degrees F, 16-ppg breaker concentration was recommended for breaking the gel. At higher temperatures (>150 degrees F), 8-ppg breaker concentration was enough to help degrade the gel.

▼ The capabilities of different types of nanoparticles (NPs) had been exploited to develop a water-based drilling fluid having better characteristics for harsh drilling conditions. More specifically, the objectives of this work are to: 1) investigate the effectiveness of using different oxide NPs: ferric oxide (of sizes< 50 nm), magnetic iron oxide (of average particle size 50 –100 nm), silica NPs (size =12 nm), and zinc oxide NPs (of sizes < 100 nm) on the rheological properties and filter cake characteristics of Ca-bentonite-based drilling fluid at downhole conditions, 2) conduct a sensitivity analysis of the rheological properties of these drilling fluids and investigate the effect of charge potential, 3) determine the optimum concentration of NPs, and 4) evaluate the effect of different drilling fluid additives on the performance of NPs/Ca-bentonite fluids by formulating and testing a complete bentonite-based drilling fluid formula. A reduction of 43% in the fluid loss volume was achieved when using 0.5 wt% of ferric oxide NPs with 7 wt% Ca-bentonite suspension compared to that without NPs. However, using silica or zinc oxide NPs at different concentrations resulted in an increase in the fluid loss volume and filter cake thickness. The inductively coupled plasma (ICP) analysis of the filtrate fluids and the scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) of the filter cakes revealed the replacement of the cations dissociated from the Ca-bentonite by ferric oxide NPs at the investigated conditions, which promoted the formation of rigid clay platelet structure. Furthermore, using 0.5 wt% of NPs provided less agglomeration, as shown by the SEM images, and less filter cake permeability. Moreover, the produced filter cake consisted of two layers, as indicated by the computed-tomography (CT) scan. Increasing the concentration of NPs resulted in an increase in the fluid loss and filter cake thickness. At high NP concentration (2.5 wt%), a new layer of the agglomerated NPs generated in the filter cake close to the surface of formation, which adversely affected the cake characteristics. The ferric oxide and magnetic iron oxide NPs/Ca-bentonite fluids were found to have stable rheological properties at different NP concentrations and temperatures (up to 200°F). Additionally, thermally aging these fluids at 350°F for 16 hours showed minor changes in their rheological properties, which confirmed their applicability in drilling downhole environments. The ferric oxide NPs improved the filter cake and filtration properties of Ca-bentonite-based drilling fluids in the presence of polymer and other additives under both static and dynamic filtration (at 100 rpm). The best filter cake characteristics were obtained when using a NP concentration of 0.3-0.5 wt%. Furthermore, the formulated NPs/Ca-bentonite-based drilling fluids could withstand downhole conditions up to 500 psi and 350°F and produced a filter cake that has 0.151-in. thickness, 6.9 ml filtrate loss volume, and 0.428 µd permeability at this… Advisors/Committee Members: Nasr-El-Din, Hisham A (advisor), Schubert, Jerome (committee member), Hascakir, Berna (committee member), El-Halwagi, Mahmoud (committee member).

Biotehničke nauke - Prehrambena tehnologija / Biotechnical Sciences - Food Technology

Zbog značajne nutritivne vrednosti i visokog sadržaja proteina, antioksidanasa i nezasićenih masnih kiselina soja se svrstava u kategoriju funkcionalne hranu. Zdravstveni efekti soje u humanoj ishrani su brojni: doprinosi smanjenju koncentracije glukoze i holesterola u krvi, pokazuje antioksidativni efekat, povoljno utiče na održavanje hormonske ravnoteže, sprečava osteoporozu i deluje preventivno na različite tipove kancera. Na tehnološki značajne funkcionalne osobine proteina semena soje najviše utiču dva glavna rezervna proteina: glicinin (11S protein) i β konglicinin (7S protein). I 11S i 7S proteini se javljaju u više izoformi. Molekul glicinin čine dva neglikozilovana heksamera koji se sastoje iz parova kiselih i baznih polipeptida povezanih disulfidnim mostom.β konglicinin je glikozilovani trimerni protein koji se sastoji iz tri podjedinice- α, α' i β. Pojedine sorte soje, među kojima su naročito brojne domaće sorte, sintetišu dodatnu β' podjedinicu. Premda je efekat ostalih podjedinica β konglicinina na tehnološka funkcionalna svojstva proteina soje intenzivno proučavan, u literaturi postoji veliki broj kontradiktornih podataka. O efektima β' podjedinice na rastvorljivost, emulgujuća i gelirajuća svojstva sojinih proteina veoma malo se zna. Cilj ovog rada bio je da se ispita efekat polipeptidnog sastava glicinina i β konglicinina na rastvorljivost, emulgujuća i gelirajuća svojstva proteina na različitim pH vrednostima (3, 5, 6 i 8) na seriji od 9 različitih genotipova soje gajenih u dve sukcesivne godine. Uspostavljanje korelacija između specifičnih podjedinica sojinih proteina i željenog svojstva pri datoj pH vrednosti, omogućilo bi ne samo selekciju sorti pogodnih za dati tehnološki proces, već bi uticalo i na osobine gotovih proizvoda. Povećana rastvorljivost obezbeđivala bi lakše usvajanje aminokiselina i bolju svarljivost. Pored povećane biološke vrednosti, visoka rastvorljivost je u pozitivnoj korelaciji sa funkcionalnim svojstvima poput geliranja i penivosti...

▼ Reducing sodium content in bread is a challenging proposition since sodium chloride contributes to more than saltiness perception in bread products. The objective of this study was to assess the effect of salt substitutes and fermented products (wheat-soybean tempe flour and sourdough) on flavor profile and rheological properties of bread. Tempe is an Indonesian traditional fermented food which is made by fungi fermentation of soybeans and other legumes.The desirable taste, flavor, texture, acidity and aroma are produced by the hydrolysis of substrates by enzymes. Sourdough process is very simple and is based on naturally occurring yeasts in the cereal grains. A commercial wheat flour with protein content 11 ± 0.5% was treated with sourdough (0, 11, 17 and 33% w/w) and tempe (0, 2, 3.5 and 5% w/w) and baked. Three sensory analysis sessions were conducted to determine the seven parameters flavor profile by 80 untrained panelists. This study showed that for saltiness score, the combination of 17% sourdough, 3.5%, panelists could not detect the difference in saltiness perception between 0.75 and 1.5% NaCl. One commercial wheat flour with protein content 11.8% was treated with different levels sodium chloride (0.75, 1.5 and 2.0%), wheat-soybean tempe flour (2 and 3.5%) and sourdough (17 and 33%) following a Randomized Complete Block Design with 3 replicates to analyze the rheological properties. Increase in development time, stability time and breakdown time was observed with elevation of NaCl levels. Development time and breakdown time decreased with increase in sourdough (17 vs 33%). A set of three commercial wheat flours with protein content 9.8, 10.9 and 13.4% was treated with sodium chloride (control) as well as five commercial NaCl substitutes following a Randomized Complete Block Design with 3 replicates to analyze the effect on rheological properties. Mixing properties showed that development time and stability time were directly proportional to the level of salt. Maximum resistance to extension (Rmax) and area under the curve increased with an increase of NaCl level. NaCl resulted in a higher area than commercial NaCl substitutes when each level of salt was analyzed.

▼ Les inhalateurs à poudre sèche (DPI) sont une alternative attractive aux inhalateurs pressurisés à valve doseuse (pMDI) du fait de leur absence de gaz propulseur. Pour pénétrer dans les poumons profonds, la taille optimale du principe actif est généralement inférieure à 5 μm. Leur mélange avec un transporteur de taille plus importante, principalement le lactose alpha monohydrate, est classiquement utilisé pour améliorer leur écoulement, faciliter le remplissage dans les inhalateurs et améliorer leur dispersion. Cependant, la formulation et la production des mélanges de poudres pour inhalation demandent une optimisation adéquate pour des-agglomérer les particules cohésives de principe actif et assurer l’homogénéité de ces mélanges contenant un faible pourcentage de principe actif (1,5 à 2,5 %). De plus, l’amélioration de la performance aérodynamique de ces mélanges est nécessaire. Le contrôle des propriétés physico-chimiques du principe actif et du transporteur est critique pour atteindre et maintenir la qualité de la formulation des poudres pour inhalation. Dans cette étude, le lactose alpha monohydrate est utilisé comme transporteur. Des lactoses de grade et de qualité différents sont comparés. Le propionate de fluticasone et le sulfate de terbutaline sont utilisés comme principes actifs modèles. Différentes techniques sont utilisées pour caractériser les principes actifs et les transporteurs: la distribution granulométrique mesurée par la méthode de diffraction laser, les propriétés thermiques par la méthode de calorimétrie (DSC), l’analyse d’image par microscopie électronique à balayage (MEB), l’énergie de surface par la méthode de chromatographie gazeuse inverse (iGC)…Le mélange principe actif et transporteur est réalisé grâce au mélangeur type Turbula, l’influence des conditions opératoires a été étudiée. La performance aérodynamique est évaluée par l’impacteur à cascade en verre (Pharmacopée Européenne). Nous avons développé des techniques de caractérisation des mélanges : l’évaluation de l’adhésion par le tamiseur à dépression d’air, la perméabilité des poudres mesurée par le perméabilimètre de Blaine ; la taille des agglomérats de principe actifs déterminée par la méthode de diffraction laser en milieu liquide. Enfin, les propriétés rhéologiques de poudre et en particulier sa fluidisation sont évaluées par un nouveau rhéomètre, le Freeman FT4. La taille des particules de transporteur exerce une influence importante sur la performance des mélanges pour inhalation. La réduction de taille du transporteur diminue les interactions entre le principe actif et le transporteur. Le détachement du principe de son transporteur est ainsi facilité ce qui augmente le pourcentage de principe actif susceptible de pénétrer dans les poumons c’est-à-dire la fraction respirable de principe actif. Différents grades et qualités de lactose de répartition granulométrique similaire mais obtenus par différentes méthodes de production ont été étudiés et comparés. Ces lactoses différaient essentiellement par le procédé de… Advisors/Committee Members: Flament, Marie-Pierre (thesis director).

In spite of the fact that there are many advantages of alkali activated materials (also called geopolymers) over the cement-based materials, geopolymer concrete has been used in the past for construction purposes on a very limited level. Among the many advantages of geopolymers compared with the cement-based materials is less CO2 emission, it uses byproducts as a binder, less energy consumption during its production, more durable as a material, fast setting time and high strength development. This work is an attempt to exert some light on the usability and applicability of geopolymers in the field of construction with concentration on its use in the 3D printing. The main aim of this study is to propose a design methodology for geopolymer paste mixture to be used in 3D printing process. For achieving this goal, one paste mixture design was selected among six ones on the bases of longer workability/flowability, suitable extrudability and specific setting time. These six designs have different binder ratios. The selected mixture design, named S20, was tested further to find out its suitability for 3D printing process. This S20 mixture was tested on compressive strength, setting time, rheological properties, open time, buildability and 28 days tensile bonding strength of two layers. To find the best suitable design, modifications were done on the S20 mixture by changing the ratios between the used alkaline solutions Na2SiO3 and NaOH (0.25 was selected). These alkaline solutions played a major role in delaying the initial setting time for rheological tests (90 minutes were selected) and the extrudability for the 3D printing process. Another factor for the best design is the Acti-gel as an additive. This additive has a direct link with the buildability, extrudability and viscosity when added with different percentages. The best selected percentage of the Acti-gel was 0.75% for this mixture design. The open time and the 28 days tensile bonding strength tests were selected to be 33 minutes and 1.32 MPa respectively. Comparing the measured plastic viscosity to the open time test, the extrudability of the mixture is not anymore valid beyond 8.8 Pa.s plastic viscosity. This short open time of 33 minutes for such geopolymer mixture design needs a fast-performing 3D printer. This might help in achieving construction projects within short time.

▼ Crumb rubber is widely used as an environment-friendly material in asphalt industry to improve pavement performance properties. Warm mixture asphalt (WMA) refers to the technologies which allow a substantial reduction of mixing and compaction temperatures of asphalt mixtures through decreasing the viscosity of asphalt binders. In general, the crumb rubber modified (CRM) asphalt mixes require higher temperatures compared to conventional hot mix asphalt (HMA). However, if the technologies of WMA are incorporated, it is predicted to reduce the mixing and compaction temperatures of rubberized asphalt mixtures. For utilization of rubberized mixes in WMA industry, it is needed to investigate the properties of CRM binders with warm additives depending on CRM contents, additive types, aging states, and other experiment variables. This research investigated CRM binders with wax warm additives, and the objectives included: 1) quantifying viscosity changes dependent upon mixing temperature and hauling period through Rotational viscometer test; 2) evaluating the effect of blending time on viscosity; 3) investigating the performance properties of recycled aged CRM binders containing wax additives through Superpave binder tests; 4) evaluating the microstructural properties using an environmental scanning electron microscope (ESEM) and an atomic force microscopy (AFM). The following conclusions were drawn based on the comprehensive laboratory investigation: 1) crumb rubber contents and wax types were found to have significantinfluence on the viscosity properties of CRM binders; 2) CRM binder with wax additive (LEADCAP) showed better rutting and cracking resistance compared to the control CRM binder for all aging states; 3) the wax additive in recycled CRM binder is observed to play an important role in binder properties even after subjecting to long-term aging processes; 4) the microstructures on morphology images seemed to have a good relation with the engineering properties of warm CRM binders.

▼ The role of carboxymethylcellulose (CMC) in association to calcium carbonate particles (CaCO3) in most water-based drilling fluids is to reduce the fluid loss to the surrounding formation. Another essential function is to provide rheological properties capable of maintaining in suspension the cuttings during drilling operation. Therefore, it is absolutely essential to correlate the polymer chemical structure (degree of substitution, molecular weight and distribution of substituent) with the physical-chemical properties of CaCO3, in order to obtain the better result at lower cost. Another important aspect refers to the clay hydration inhibitive properties of carboxymethylcellulose (CMC) in drilling fluids systems. The clay swelling promotes an undesirable damage that reduces the formation permeability and causes serious problems during the drilling operation. In this context, this thesis consists of two main parts. The first part refers to understanding of interactions CMC-CaCO3, as well as the corresponding effects on the fluid properties. The second part is related to understanding of mechanisms by which CMC adsorption occurs onto the clay surface, where, certainly, polymer chemical structure, ionic strength, molecular weight and its solvency in the medium are responsible to affect intrinsically the clay layers stabilization. Three samples of carboximetilcellulose with different molecular weight and degree of substitution (CMC A (9 x 104 gmol DS 0.7), CMC B (2.5 x 105 gmol DS 0.7) e CMC C (2.5 x 105 gmol DS 1.2)) and three samples of calcite with different average particle diameter and particle size distribution were used. The increase of CMC degree of substitution contributed to increase of polymer charge density and therefore, reduced its stability in brine, promoting the aggregation with the increase of filtrate volume. On the other hand, the increase of molecular weight promoted an increase of rheological properties with reduction of filtrate volume. Both effects are directly associated to hydrodynamic volume of polymer molecule in the medium. The granulometry of CaCO3 particles influenced not only the rheological properties, due to adsorption of polymers, but also the filtration properties. It was observed that the lower filtrate volume was obtained by using a CaCO3 sample of a low average size particle with wide dispersion in size. With regards to inhibition of clay swelling, the CMC performance was compared to other products often used (sodium chloride (NaCl), potassium chloride (KCl) and quaternary amine-based commercial inhibitor). The low molecular weight CMC (9 x 104 g/mol) showed slightly lower swelling degree compared to the high molecular weight (2.5 x 105 g/mol) along to 180 minutes. In parallel, it can be visualized by Scanning Electron Microscopy (SEM) that the high molecular weight CMC (2.5 x 105 g/mol e DS 0.7) promoted a reduction in pores formation and size of clay compared to low molecular weight CMC (9.0 x 104 g/mol e DS 0.7), after 1000 minutes in aqueous medium.… Advisors/Committee Members: Balaban, Rosângela de Carvalho (advisor), CPF:65946499734 (advisor), http://lattes.cnpq.br/7711521318854102 (advisor).

Another important aspect refers to the clay hydration inhibitive properties of carboxymethylcellulose (CMC) in drilling fluids systems. The clay swelling promotes an undesirable damage that reduces the formation permeability and causes serious problems during the drilling operation. In this context, this thesis consists of two main parts. The first part refers to understanding of interactions CMC-CaCO3, as well as the corresponding effects on the fluid properties. The second part is related to understanding of mechanisms by which CMC adsorption occurs onto the clay surface, where, certainly, polymer chemical structure, ionic strength, molecular weight and its solvency in the medium are responsible to affect intrinsically the clay layers stabilization. Three samples of carboximetilcellulose with different molecular weight and degree of substitution (CMC A (9 x 104 gmol DS 0.7), CMC B (2.5 x 105 gmol DS 0.7) e CMC C (2.5 x 105 gmol DS 1.2)) and three samples of calcite with different average particle diameter and particle size distribution were used. The increase of CMC degree of substitution contributed to increase of polymer charge density and therefore, reduced its stability in brine, promoting the aggregation with the increase of filtrate volume. On the other hand, the increase of molecular weight promoted an increase of rheological properties with reduction of filtrate volume. Both effects are directly associated to hydrodynamic volume of polymer molecule in the medium. The granulometry of CaCO3 particles influenced not only the rheological properties, due to adsorption of polymers, but also the filtration properties. It was observed that the lower filtrate volume was obtained by using a CaCO3 sample of a low average size particle with wide dispersion in size. With regards to inhibition of clay swelling, the CMC performance was compared to other products often used (sodium chloride (NaCl), potassium chloride (KCl) and quaternary amine-based commercial inhibitor). The low molecular weight CMC (9 x 104 g/mol) showed slightly lower swelling degree compared to the high molecular weight (2.5 x 105 g/mol) along to 180 minutes. In parallel, it can be visualized by Scanning Electron Microscopy (SEM) that the high molecular weight CMC (2.5 x 105 g/mol e DS 0.7) promoted a reduction in pores formation and size of clay compared to low molecular weight CMC (9.0 x 104 g/mol e DS 0.7), after 1000 minutes in aqueous medium.… Advisors/Committee Members: Balaban, Rosângela de Carvalho (advisor), CPF:65946499734 (advisor), http://lattes.cnpq.br/7711521318854102 (advisor).

▼ The need to automate the construction process for civil infrastructures has been perpetually propelled by the reported number of detrimental site accidents, enormous time, and material wastages in the current labor-intensive approaches. Additive 3D printing applications in the construction sector could revolutionize the construction sites. The 3D printing technologies will be an eco-friendly variant and will relax the formwork requirement, giving wider build customizability when compared to the traditional construction methods. The notable advantages of 3D printing over conventional construction techniques include safer work ambiance, reduced cost and time for construction. The first objective of this research work is to identify the concrete mixture that is readily available for 3D printing and establish their material characteristics. This work serves up a model schema for researchers to look up and identify desired mixture properties for instantaneous concrete printing. In this study, ready-to-print fresh cementitious mixtures were characterized for printability and buildability based on their rheological and mechanical properties. Admixtures such as Silica fume and Superplasticizer were added to the ordinary Portland cement in different proportions to test and improve the yield stress and attain the desired viscosity for 3D printing. The other objective is to study the impacts of using different nozzle geometries in the printed constructs. In the additive 3D printing process, choosing the right nozzle geometry before printing is critical as it affects the surface finish as well as the mechanical properties of the constructs. This study utilizes point cloud data of the printed samples obtained from Structured Light System- a scanning technique to measure the contour deviation and surface roughness. The compression strength of the mixtures was determined to explore the mechanical properties, by conducting compression tests as per the ASTM standards. A comparative study on the compression strength of 3D printed constructs with precast was made to identify the impacts of nozzle geometry in the compression strength. To summarize, a concrete extrusion system has been built and the concrete flow properties that are desirable for instantaneous 3D printing have been identified. The rheological properties, printability, and buildability of all the identified concrete mixtures were evaluated and the best mixture proportions were advanced for printing constructs. The nozzle geometry study has established the impacts on the contour as well as the mechanical properties on the constructs, and hence urging the need to choose the right nozzle geometry before 3D printing.

Prehrambena tehnologija - Tehnologija ratarskih proizvoda / Food technology - Technology of crop products

Prehrambeni proizvodi koji sadrže probiotske mikroorganizme, uglavnom bakterije mlečne kiseline, sa pozitivnim učincima po zdravlje, predstavljaju jedno od najvećih tržišta funkcionalne hrane, među kojima su proizvodi od mleka najdostupniji. Težnja da korisne, probiotske bakterije bezbednije i lakše prežive uslove gastrointestinalnog trakta, kao i potreba da budu dostupne tokom dužeg vremenskog perioda u odnosu na onaj koji je ograničen trajnošću proizvoda od mleka, nametnula je ideju da se obave opsežnija ispitivanja primene probiotika na čokoladi kao nosaču. Program istraživanja u okviru ove doktorske disertacije bio je usmeren na ispitivanje mogućnosti primene probiotika u različite vrste čokolada, zbog njihove osetljivosti prema velikom broju procesnih faktora i uslovima okoline, a imajući u vidu da je održivost esencijalno svojstvo koje uslovljava njihovu efikasnost. Inkluzijom probiotskih kultura uvodi se dodatna disperzna faza u sastav čokolada, što može imati uticaja na njihovu mikrostrukturu i usloviti promene izgleda - boje, teskture, topivosti i reoloških svojstava. Pored navedenog, pojedina istraživanja ukazuju na mogućnost postojanja interakcija između probiotskih mikroorganizama i polifenolnih komponenata namirnice u koje su dodati, što može dovesti do promene njenog antioksidativnog kapaciteta. Kako bi se ustanovilo u kojoj meri je inkorporiranje probiotika uticalo na dominantna svojstva različitih vrsta čokolada, obavljeno je ispitivanje njihovih senzornih, antioksidativnih i reoloških karakteristika neposredno nakon proizvodnje (0-30 dana) i tokom skladištenja od 90, odnosno 180 dana. Radi utvrđivanja svih faktora koji mogu uticati na funcionalnost čokolada sa probioticima obavljene su i analize upotrebljenih ambalažnih materijala, koje su obuhvatale ispitivanje fizičkomehaničkih i barijernih svojstava...

▼ The purpose of this study is to identify and quantify factors governing extrudate swell and melt fracture. In the first part, the factors which control the extrudate swell of carbon black (N330) filled styrene-butadiene rubber (SBR) compounds at various states-of-mix were investigated. State-of-mix is quantified by effective filler volume fraction (EFVF), based on an estimate of the amount of rubber immobilised in the carbon black agglomerates. Extrudate swell was found to be dominated by recoverable strain and relaxation time, which are controlled by EFVF. In contrast, shear rate and the rubber-carbon black tridimensional transient network were not found to influence extrudate swell significantly. In the second part, melt fracture of the rubber compounds was investigated in terms of surface texture wavelength. The longer the wavelength, the greater the severity of the surface disruption. It was found that wavelength was controlled strongly by state-of mix (or by EFVF). In addition, a mechanism for melt fracture of the compounds studied has been proposed, based on average energy at the extrudate surface (t.E). Lastly, the influences of additives; paraffinic processing oil, stearic acid or a mixture of predominantly calcium fatty acid soaps on extrudate swell and melt fracture were investigated. For the rubber compounds with paraffinic processing oil or stearic acid, EFVF was found to play an important role in extrudate swell. The mixture of fatty acid soaps was shown to reduce significantly extrudate swell due to the presence of wall slip. The influence of the fatty acid soaps on extrudate swell is more noticeable for extrudates obtained from long dies, in which flow is dominated by shear. The major factors shown to exert a significant influence on melt fracture for the compounds with paraffinic processing oil or stearic acid are EFVF and green strength of the extrudate. Wall slip, promoted by a mixture of fatty acid soaps, was also found to decrease the melt fracture severity, particularly for long dies in which shear stresses are dominant.

▼ Foamed asphalt (water-foamed asphalt in this study) is formed by combining hot asphalt with a small amount of cold water, while emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (or surfactant). The foaming and emulsifying processes are the water-based physical and chemical processes in decreasing the apparent viscosity of asphalt, respectively. Both foamed and emulsified asphalt materials containing some free water, and have been widely used in the cold, half-warm, and warm mix asphalt productions. Also, the pavement surface treatments and maintenances are involved in these asphalt materials. However, it is limited to a profound understanding of mechanical performance and corresponding physicochemical properties. The objectives of this study are 1) to characterize the rheological properties of foamed and emulsified asphalt materials, 2) and to evaluate the mechanical properties of its mixtures in the applications of pavement construction, surface treatments, and pavement maintenances. The rheological behavior of foamed asphalt was measured at various temperatures and with different water content can provide the apparent viscosity and agitation torque of the foamed asphalt. Besides, according to the dynamic foaming processes of the foamed asphalt, this study successfully applied the dynamic movement of water vapor or bubble in foamed asphalt to disperse the nano hydrated lime (NHL) particles in the suspensions into the asphalt. The dispersion condition and the microstructure of the nanoparticles in the asphalt were evaluated via scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. A surfactant of sodium dodecylbenzene sulfonate was added to the water to form suspensions before inserted into the hot asphalt. Also, the study characterized the impacts of the foaming condition and the multiple freeze-thaw cycles on the laboratory tensile strength tests via Materials Testing System (MTS) of the foamed asphalt mixtures. Then, the nondestructive ultrasonic direct test was applied to assess the foamed asphalt mixture damage level after the multiple freeze-thaw cycles. Meanwhile, for another kind of asphalt material containing free water (emulsified asphalt), the interactions of asphalt and water in the emulsified asphalt were characterized first. The moisture (or water) retention of emulsified asphalts during the oven heating was applied to assess the emulsification stability at different acidic and alkaline levels. The dynamic shear rheometer (DSR) experiments characterized the apparent viscosity and rutting indicator as to the parameters for expressing the rheological properties of both emulsified asphalts and the individual residues. The Fourier-transform infrared spectroscopy (FT/IR) analyzed the interactions of asphalt and water in emulsified asphalt from the perspective of molecular chemistry. After that, the application of emulsified asphalt on pavement maintenance; the example of chip-seal was… Advisors/Committee Members: Zhanping You, Qingli Dai.

▼ Oxidative aging is a major issue in asphalt pavements that leads to hardening of the asphalt, which further contributes significantly to asphalt pavement embrittlement and eventually results in excessive pavement cracking. In addition, the performance of asphalt binder is also highly related to its service conditions which involve climatic conditions and traffic conditions, such as temperature, moisture and traffic loads. Generally, the mechanical properties of asphalt before and after oxidative aging can be tested in the laboratory; however, the fundamental material science of asphalt before and after oxidative aging is difficult to be investigated in the laboratory regarding chemical composition and property change due to the difficulties of studying the molecular structures and their dynamic behavior in asphalt. Therefore, Molecular Dynamics (MD) simulation method is used in this study to understand how the chemical composition and property changes of asphalt after oxidative aging affect the physical, thermodynamic, rheological and mechanical performance of the asphalt, and how the oxidized asphalt acts under different conditions, such as loading, temperature, and moisture, compared to the unoxidized asphalt. MD simulation is a computational method used to simulate the physical movements of atoms and molecules depending on time and force field chosen under different conditions, such as temperature, pressure, and loading. Asphalt models before and after oxidative aging are developed for MD simulations in this study under different temperatures, loading and moisture contents. Simulation results show that the oxidized functional groups in asphalt molecules increase the strength of intermolecular bonds of asphalt, which further contributes to the hardening of the oxidized asphalt. Specifically, the internal energy changes, especially for higher magnitude of intermolecular and lower kinetic energies, are responsible for the hardening of oxidized asphalt, and the higher potential energies and for oxidized asphalt further proves that oxidation increases the polarity of molecules in asphalt and forms strongly interacting components. The internal property change is consistent with the external physical and rheological property change after oxidation, which is revealed by the increase of density, bulk modulus and viscosity. Considering the mechanical property of asphalt using MD simulations, both the unoxidized and oxidized asphalts deform more and fail faster with an increase in both compressive and tensile stress rates, especially under tensile stresses. However, the oxidized asphalt is stiffer than the unoxidized asphalt, which shows slower and less deformation, further validating the hardening of asphalt after oxidation. Asphalt is significantly susceptible to temperature. Simulation results show that density, and zero shear viscosity of asphalt decrease with an increase in temperature. Isothermal compressibility and bulk modulus also change under different temperatures. Moreover, the density, bulk modulus (inverse of… Advisors/Committee Members: Tarefder, Rafiqul, Shen, Yu-Lin, Ng, Tang-Tat, Zhang, Guohui, Tarefder, Rafiqul.
