초록

A cement admixture comprising a polymer latex and a water reducing agent as effective components, wherein the polymer latex comprises a copolymer of monomers comprising ethylene, vinyl acetate and an acrylic ester, and an emulsion stabilizer, said emulsion stabilizer being a surfactant.

대표청구항 ▼

A cement additive admixture comprising a polymer latex and a soluble water reducing agent wherein the copolymer latex comprises a copolymer of monomers comprising ethylene, vinyl acetate and an acrylic ester, in a ratio of 98:2 to 10:90 by weight of copolymer latex solids to the soluble water reducing agent, said soluble water reducing agent being an additive to cement capable of reducing the required water/cement ratio for achieving a specified fluidity for the cement additive admixture, an emulsion stabilizer for stabilizing the copolymer latex, said emulsion stabilizer being a surfactant which is an anionic, cationic, or nonionic surfactant, and inorganic ultrafine particles wherein the ratio of solid content of the copolymer latex to the ultrafine particles is 95:5 to 5:95 by weight, said ultrafine particles having an average particle size smaller than the particle size of the cement.
