水硬性組成物の硬化体の製造方法
Document Type and Number:
Japanese Patent JP6821250
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a hardened body of a hydraulic composition capable of obtaining a hardened body having beautiful surface appearance and strength.SOLUTION: There is provided a method for producing a hardened body of a hydraulic composition comprising (A) a thickener, (B) a polycarboxylic acid-based dispersant, a hydraulic powder and water, in which a hydraulic composition used for producing a hardened body is divided and filled in the same molding flask, vibration is applied to the hydraulic composition in the molding flask in each filling operation and other hydraulic compositions are filled in the same molding flask before the hydraulic composition previously filled in the molding flask is cured. The thickener (A) preferably includes an unsaturated carboxylic ester polymer, an unsaturated carboxylic acid polymer and an unsaturated carboxylic acid amide polymer and the polycarboxylic acid-based dispersant (B) preferably is a polycarboxylic acid-based dispersant having a polyoxyalkylene chain having an average addition mole number of 30 to 300, especially preferably a polycarboxylic acid-based polymer.SELECTED DRAWING: None
