ADDITIVE COMPOSITION FOR HYDRAULIC COMPOSITION CONTAINING LATENT HYDRAULIC POWDER
To provide an additive composition for a hydraulic composition containing latent hydraulic powder, which enables the resulting hydraulic composition to exhibit excellent fluidity upon being vibrated and to yield a hardened material of the hydraulic composition, having an excellent surface appearance, even when hydraulic powder containing latent hydraulic powder is used.SOLUTION: The additive composition for a hydraulic composition containing latent hydraulic powder, contains the following component (A), in which the component (A) is a copolymer including, as its constituent monomers, a monomer (1a) selected from acrylic acid, methacrylic acid and a salt thereof, a monomer (2a) selected from an acrylic ester and a methacrylic ester, and a crosslinking monomer (3a) comprising two or more vinyl groups, with the ratio of the monomer (1a) being 5-50 mol%, the ratio of the monomer (2a) being 30-90 mol%, and the ratio of the monomer (3a) being 0.1-20 mol%, in the constituent monomers of the copolymer.SELECTED DRAWING: None
