CEMENT ADMIXTURE AND CEMENT COMPOSITION CONTAINING THE SAME
PROBLEM TO BE SOLVED: To provide a cement admixture having an increased mix speed during mixing a material of a cement composition, excellent in slump loss inhibiting performance and capable of suppressing increase of viscosity of the cement composition, and a cement composition containing the same.SOLUTION: There is provided a cement admixture containing following (A) component and (B) component. (A) component: a polycarboxylic copolymer obtained by copolymerizing 1 to 97 wt.% of a monomer (I) represented by the following general formula (1), 1 to 97 wt.% of a monomer (II) represented by the following general formula (2), 0.1 to 50 wt.% of an unsaturated carboxylic acid-based monomer (III), and 0 to 50 wt.% of another monomer (IV) or a salt thereof. R-O-(AO)-R(1). (B) component: a single polymer of hydroxy ethylacrylate (B1) and/or a single polymer of hydroxypropyl acrylate (B2).SELECTED DRAWING: None
