摘要： The present invention is directed to derivatized polycarboxylate dispersants for cementitious mixtures, including those mixtures with high percentages of pozzolan cement replacement and dry cast applications. In particular, the invention is directed to a cementitious mixture comprising cement, including cements with high percentages of pozzolan cement replacement, water, coarse aggregate, fine aggregate, and including a dispersant, wherein said dispersant is a derivatized polycarboxylate dispersant, or combination of polycarboxylate dispersants, which is a derivatized polymer comprising a backbone having moieties derived from (a) an unsaturated hydrocarbon; (b) at least one of a substituted carboxylic acid monomer, a substituted ethylenically unsaturated monomer, and maleic anhydride; and (c) optionally including an N-polyoxyalkylene succinimide; and wherein derivative moieties are pendant to the backbone monomer by at least one ester linkage and at least one amide linkage. The derivatized polycarboxylate dispersant provides for a longer shelf life dispersant, improved dispersability of cementitious mixtures, water reduction in cementitious mixtures, and is an effective dispersant in high pozzolan replaced cementitious mixtures.

摘要： A cementitious mixture comprises a hydraulic cement; greater than about 10% by weight of a pozzolanic cement replacement selected from fly ash, slag, natural pozzolans, and mixtures thereof, based on the weight of said hydraulic cement and cement replacement; and a compatabilizing admixture, wherein the compatabilizing admixture comprises a compatabilizing derivatized polycarboxylate polymer dispersant capable of acting as a water reducer, in combination with an accelerator. The derivatized polycarboxylate dispersant, alone or in combination with other derivatized polycarboxylate dispersants, is a polymer comprising units derived from at least one of a substituted carboxylic acid monomer and a substituted ethylenically unsaturated monomer, at least one of an N-polyoxyalkylene maleimide and a condensation product of an unsubstituted carboxylic acid monomer and an alkoxypolyoxyalkylene primary amine substituted carboxylic acid monomer, and optionally including an unsaturated hydrocarbon. The derivatized polycarboxylate dispersant provides for a longer shelf life dispersant, improved dispersability of cementitious mixtures, water reduction in cementitious mixtures, and is an effective dispersant in high pozzolan replaced cementitious mixtures.
