Synthesis And Characterization Of Polymer-Silica Composite Hydrogel Particles And Influence Of Hydrogel Composition On Cement Paste Microstructure, Matthew J. Krafcik, B Bose, Kendra Erk
Synthesis And Characterization Of Polymer-Silica Composite Hydrogel Particles And Influence Of Hydrogel Composition On Cement Paste Microstructure, Matthew J. Krafcik, B Bose, Kendra Erk
School of Materials Engineering Faculty Publications
The objective of this research is to define the fundamental structure-property relationships of water-swollen polymer hydrogel particles that are employed as internal curing agents in cementitious mixtures, in addition to reporting a novel synthesis procedure for combining pozzolanic materials with hydrogel particles. Solution polymerization was performed to incorporate amorphous nanosilica particles within acrylic-based polymer hydrogel particles of varying chemical compositions (i.e., monomer ratio of acrylic acid (AA) to acrylamide (AM)). Experiments were designed to measure the absorption capacity and kinetics of hydrogel particles immersed in pure water and cementitious pore solution, as well as determine the impact of particles on …

Strength And Durability Of Concrete: Effects Of Cement Paste-Aggregate Interfaces, Part Ii: Significance Of Transition Zones On Physical And Mechanical Properties Of Portland Cement Mortar, Turng-Fang F. Lee, Menashi D. Cohen
JTRP Technical Reports
This research was based on a two-part basic research investigation studying the effects of cement paste-aggregate interfaces (or interfacial transition zones-HZ) on strength and durability of concrete. Part I dealt with the theoretical study and Part II dealt with the experimental. Part I, the theoretical part, illustrates the effect of ITZ on the concrete properties by assuming its elastic moduli to be varied continuously in the region. A four-phase composite model is employed and three functions are chosen to model the moduli variation in the ITZ. A theoretical solution for an n-layered spherical inclusion model is used to estimate the …
