ABSTRACT:
When a cement dispersant comprising a polymer which is obtained by co-condensating monomers comprising monomer (A) and monomer (B) with formaldehyde, or a salt obtained by neutralizing the polymer, wherein the monomer (A) is an aromatic compound having, on the average, 1 to 300 mol per molecule of at least one member selected from the group consisting of oxyethylene group and oxypropylene group, and the monomer (B) is an aromatic compound having a carboxyl group; or another cement dispersant comprising a polymer which is obtained by co-condensating monomers comprising the above-described monomer (A), the above-described monomer (B) and monomer (C) which is an aromatic compound having a sulfonic acid group with formaldehyde, or a salt obtained by neutralizing the polymer is used as one component of a hydraulic composition, the fluidity of the hydraulic composition is maintained for a long time. Therefore, no trouble on transportation is caused during the force feeding of the hydraulic composition with a pump.
