CEMENT ADMIXTURE, CEMENT COMPOSITION AND METHOD FOR LAYING WORK THE SAME, AND METHOD FOR PRODUCING CEMENT HARDENED PRODUCT |
摘要 |
The cement admixture of the present invention can provide viscosity decreasing ability as well as a high dispersing ability and slump loss preventing ability even in a high water reducing ratio range. The above-mentioned cement admixture comprises three components of a copolymer (A) containing a constituent unit (I) derived from the unsaturated (poly)alkylene glycol ether monomer (a) and a constituent unit (II) derived from a maleic acid monomer (b), a specific unsaturated (poly)alkylene glycol ether monomer (a) and a non-polymerizable (poly)alkylene glycol (B) having no alkenyl group. |
