Abstract

Provided is a dispersion-maintaining agent for a hydraulic composition capable of maintaining the fluidity of the hydraulic composition even when a long time has elapsed since kneading and with little curing delay. A vinyl copolymer obtained by copolymerizing a specific monomer having a carboxyl group in the molecule, a specific monomer having a polyalkylene glycol residue in the molecule, and, when necessary, another monomer copolymerizable with these monomers is used as the dispersion-maintaining agent for a hydraulic composition.
