STATE-OF-THE-ART REPORT ON POLYMER-MODIFIED CONCRETE
Dispersions of polymers in water have been in use for many years as admixtures to portland cement mortar and concrete. These dispersions are commonly called latexes. The property improvements from this family of admixtures includes increased bond strength, reduced permeability, increased resistance to freezing and thawing, and increased flexural strength. The specific property improvement to the modified mortar and concrete will vary with the type of latex used. The proportioning of ingredients and mixing procedures are similar to unmodified mortars and concretes. Curing is different in that only 1 to 2 days of moist cure are required. This is followed by air drying. Applications of these materials include tile adhesive and grout, floor leveling, concrete patching, and bridge deck overlays.
