ADDITIVE FOR HYDRAULIC COMPOSITION, AND HYDRAULIC COMPOSITION
To provide an additive for a hydraulic composition capable of increasing in a strength at an initial material age (about one day of material age).SOLUTION: The additive for a hydraulic composition consists of a polycarboxylic acid-based dispersant and diethylene glycol, in which the polycarboxylic acid-based dispersant comprises a copolymer P including a structural unit, represented by the following formula(1), derived from a monomer M and an unsaturated carboxylic acid-based monomer A. (In the above formula (1), Rrepresents an alkenyl group having 2 to 5 carbon atoms or an unsaturated acyl group having 3 or 4 carbon atoms, and Rrepresents a hydrogen atom, an alkyl group having 1 to 22 carbon atoms or an aliphatic acyl group having 1 to 22 carbon atoms. X represents a polyoxyalkylene group having an average number of moles added of 40 to 160 composed of an oxyalkylene group having 2 to 4 carbon atoms.)SELECTED DRAWING: None
