Abstract

PURPOSE:To obtain a cement dispersing agent containing a specific high molecular polymer as a main ingredient and capable of preventing lowering of workability of a hydraulic cement composition with time and improving processability and workability thereof. CONSTITUTION:The aimed cement dispersing agent containing a high molecular polymer (e.g. 1-allyloxy-2,3-dihydroxypropane-acrylic acid copolymer) having 1:0.5-1:0.01 molar ratio of carboxyl group to trialkyl group and 500-300,000mol. wt. as a main ingredient. 0.1-1wt.% of the above-mentioned dispersing agent is added to a cement.
