Abstract:
1. Method for modifying a cementitious material comprising: combining with a hydratable cementitious binder a composition in which solute and solvent portions are uniformly mixed together, said composition comprising: a solute portion having at least one non-saponified hydrophobic material which is operative to enhance water repellency in said cementitious material; and a non-aqueous solvent portion having at least one glycol ether operative to inhibit drying shrinkage in said cementitious material; said solute and solvent being present in said composition in a ratio of 95:5 to 5:95; said solute and solvent portions being mixed uniformly together by dissolving said at least one non-saponified hydrophobic material in said solvent before combining with said hydratable cementitious binder, said solute and solvent portions thereby forming a non-aqueous solution or an emulsion wherein water is present as a non-continuous phase; said uniformly-mixed-together solute/solvent composition being combined with said hydratable cementitious binder either during a manufacturing process wherein clinker is transformed into hydratable cement or as an admixture to hydratable cement, concrete, or other cementitious material which forms a structure.
