摘要： To provide shrinkage reducing agents which render excellent shrinkage reducing effect and frost-thaw resistance to cement compositions such as mortar and concrete without entraining excessive air, and exhibit excellent solution stability.The shrinkage reducing agent comprises a (poly)alkylene compound having an unsaturated bond represented by the formula (1): R2O—R1—O-(A1O)n—R3 (1) -(A2O)m—R4 (2) (wherein R1 is a C2-10 hydrocarbon group having an unsaturated bond; R2 is hydrogen or the formula (2); R3 and R4 are each independently hydrogen or a C1-8 alkyl group; A1O and A2O are one or more kinds of C2-4 oxyalkylene groups; and n and m are mean addition numbers of moles of A1O and A2O, respectively, and 1 to 20).

摘要： A multi-functional cement dispersant contains a graft copolymer obtained by a graft reaction of one or more selected from polyoxyalkylene monoalkylester, polyoxyalkylene monoalkylether and polypropyleneglycol of specified kinds to a copolymer obtained by radical polymerization of a mixture of radical polymerizable monomers containing maleic anhydride and monomers of a specified kind at a specified ratio. Hydraulic cement compositions produced with such a multi-functional cement dispersant have a superior fluidity with reduced loss over time and hardened objects produced from such a composition exhibit a superior early strength and have a low dry shrinkage and a high resistance against freezing and thawing.
