Document Type and Number:
WIPO Patent Application WO/2017/069214
Kind Code:
A1
Abstract:
Provided is an additive for a non-hydraulic powder-containing composition, which can improve the flowability of the non-hydraulic powder-containing composition. Also provided is a concrete composition containing such an additive for a non-hydraulic powder-containing composition. The additive for a non-hydraulic powder-containing composition according to the present invention comprises a polycarboxylic acid-based copolymer containing 5-33 mol% of a structural unit (I) derived from a specific unsaturated polyalkylene glycol monomer (a), 1-95 mol% of a specific carboxylic acid-based structural unit, and 0-94 mol% of a structural unit (IV) derived from other monomers (d), wherein the total amount of the structural units (I), (II), and (IV) is 100 mol%.
