Chemical additives for addition to cementitious or polymeric mixtures to affect various desired changes in mixture properties, including imparting permanent bacteriostat and fungistat properties, enhanced graffiti resistance, anti-slip properties, enhanced strength, self-cleaning properties, reduced permeability, increased freeze/thaw resistance, improved workability, primarily for use in flooring and wall systems

concrete admixtures; chemical additives for addition to concrete and to cementitious mixtures to affect desired changes in properties, for example to enhance strength, and/or to reduce permeability, and/or to increase freeze/thaw resistance, and/or to improve workability, and/or to control set rate, and/or to reduce mix water requirements and/or to control air entrainment; polymerbased admixtures for addition to concrete
