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 unsaturated 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.
