<p><P>PROBLEM TO BE SOLVED: To provide an admixture for cement, with which the water reducing property of a cement composition can be improved, the strength and durability of the hardened body of the cement composition can be enhanced made excellent and the viscosity of the cement composition can be controlled so as to be handled easily at the work site, and to provide a method for manufacturing the admixture. <P>SOLUTION: This admixture contains a polyhydric alcohol alkylene oxide adduct and an unspecified polycarboxylic acid-based polymer or a specified polycarboxylic acid-based polymer which is obtained by copolymerizing a polycarboxylic acid and a polyhydric alcohol alkylene oxide adduct. <P>COPYRIGHT: (C)2004,JPO</p> |
