ADDITIVE FOR NON-HYDRAULIC POWDER-CONTAINING COMPOSITION, AND CONCRETE COMPOSITION
PROBLEM TO BE SOLVED: To provide an additive for a non-hydraulic powder-containing composition capable of improving fluidity of a non-hydraulic powder-containing composition, and to provide a concrete composition containing the additive for a non-hydraulic powder-containing composition.SOLUTION: The additive for a non-hydraulic powder-containing composition according to the present invention is an additive to be used for a non-hydraulic powder-containing composition, the additive comprising a polycarboxylic acid-based copolymer containing: 1-35 mol% of a structural unit (I) derived from a specific unsaturated polyalkylene glycol-based monomer (a); 0-98 mol% of a specific carboxylic acid-based structural unit (II); 1-99 mol% of a specific calcium carboxylate-based structural unit (III); and 0-34 mol% of structural units (IV) derived from other monomers (d). The total of the structural unit (I), the structural unit (II), the structural unit (III), and the structural units (IV) is 100 mol%, and the total of the structural unit (II) and the structural unit (III) is 65-99 mol%.SELECTED DRAWING: None
