Cement dispersing agent and concrete composition comprising same |
| abstract |
A cement dispersant which comprises a water-soluble amphoteric copolymer produced from ingredients including an unsaturated polyamide-polyamine/alkylene oxide adduct and two or more polyalkylene glycol esters. After the dispersant is kneaded together with a concrete composition, the dispersing ability thereof increases with time. It is highly effective in reducing concrete viscosity. [MEANS FOR SOLVING PROBLEMS] The cement dispersant composition comprises as an essential ingredient either a water-soluble amphoteric copolymer obtained through copolymerization from (A) an unsaturated polyamide-polyamine/alkylene oxide adduct, (B) (meth) acrylic acid or an alkali metal salt or ammonium or alkanolamine salt thereof, (C) a polyalkylene glycol ester of methacrylic acid, and (C) a polyalkylene glycol ester of acrylic acid or a neutral salt of the copolymer. |
