HYDRAULIC COMPOSITION FOR CENTRIFUGAL MOLDING

摘要

The present invention pertains to a hydraulic composition for centrifugal molding, the hydraulic composition containing, for example: (A1) a cationic polymer having a weight average molecular weight of 1,500-300,000 and having a quaternization degree of 5-100%; (B) a polycarboxylic acid-based dispersant; a hydraulic powder; an aggregate; and water. The present invention also pertains to a hydraulic composition for centrifugal molding, the hydraulic composition containing: (A2) a compound which is a polymer or copolymer having acrylic acid and/or maleic acid as constituent monomers and has an unneutralized carboxyl group; (B2) a polycarboxylic acid-based dispersant having an unneutralized carboxyl group; a hydraulic powder; an aggregate; and water. The present invention also pertains to a hydraulic composition for centrifugal molding, the hydraulic composition containing: (A3) a polymer or copolymer having acrylic acid and/or maleic acid as constituent monomers; (B1) a polycarboxylic acid-based dispersant; (C) a Brønsted acid; a hydraulic powder; an aggregate; and water.
