摘要： Amine solubilizing agents are mixed with water insoluble defoamers and optionally a dispersant for cementitious compositions to provide an admixture for cementitious compositions that is stable over time. A cementitious composition is provided that includes cementitious material, water, a water insoluble defoamer, optionally a dispersant for cementitious compositions, and an amine solubilizing agent that solubilizes the water insoluble defoamer. A method is provided for making a cementitious composition that includes mixing cementitious material, water, a water insoluble defoamer, an amine solubilizing agent that solubilizes the water insoluble defoamer, and optionally a dispersant for cementitious compositions.

摘要： A dry cast article and method for making the same, wherein the dry cast article includes an oligomeric dispersant that is a reaction product of two or three moieties is provided. To make a dry cast article, hydraulic cement, water, coarse aggregate, fine aggregate, optionally a surface active agent/air entraining agent, and an oligomeric dispersant are mixed and used to form a dry cast article from the mixture.

摘要： The present invention is directed to cementitious dry cast mixtures for forming cementitious articles, particularly a cementitious dry cast mixture containing a dispersant, wherein said dispersant is a derivatized polycarboxylate dispersant which is a polymer comprising units derived from at least a substituted carboxylic acid monomer or substituted ethylenically-unsatured monomer, and optionally including at least one of an unsaturated hydrocarbon, an N-polyoxyalkylene maleimide, and a condensation product of an unsubstituted carboxylic acid monomer and an alkoxypolyoxyalkylene primary amine substituted carboxylic acid monomer. The cementitious dry cast mixture has a reduced effective dose of dispersant; compacts and consolidates in response to vibration energy; reduces the cycle time in the production of articles manufactured from dry cast mixtures; provides for increased green strength, density, and early compressive strength; and improves the surface aesthetics of articles manufactured from dry cast mixtures. Additionally, a surface active agent/air entraining agent can be included in combination with the dispersant to provide for increased swipe effect.
