CEMENT ADMIXTURE FOR FABRIC FORM, CEMENT COMPOSITION, AND METHOD FOR CONSTRUCTING FABRIC FORM

摘要

PROBLEM TO BE SOLVED: To provide a cement admixture capable of preparing cement concrete which has excellent filling property into a fabric form because of holding fluidity with excellent work efficiency, and has quick coagulation after press-fitting or filling to thereby dispense with reinforcement of the fabric form, and also has no risk of overflow of alkali water into a river or the underground because excess water is greatly reduced.;SOLUTION: A cement admixture for a fabric form contains calcium aluminosilicate, gypsum, a cellulose derivative and a polycarboxylic acid-based water reducer as essential components. A cement composition containing the admixture, and a method for constructing a fabric form obtained by press-fitting cement concrete containing the cement composition into the fabric form are also provided.;COPYRIGHT: (C)2013,JPO&INPIT
