ADDITIVE FOR DEOPOLYMER AND DEOPOLYMER CURED BODY

摘要

PROBLEM TO BE SOLVED: To provide a novel additive for geopolymer for providing a cured body capable of not only adjusting setting time of geopolymer and securing flowability before curing and strength development of the cured body, but also inhibiting dry constriction.SOLUTION: There is provided an additive for geopolymer containing a constriction reducing agent containing an ether compound having a structure represented by the following general formula (1):-O-(AO)n- (1), where AO represents a bivalent alkylene oxide group, n represents average additive molar number of the alkylene oxide and the number of 1 to 200, and a constriction reducing assistant for geopolymer containing one or more kind of salt of aliphatic oxycarboxylic acid having hydroxyl group value of 250 to 1500 mgKOH/g and acid value of 250 to 950 mgKOH/g and having mass weighted average value of hydroxyl group/acid group of the aliphatic oxycarboxylic acid of 0.40 or more and less than 5.00, the constriction reducing assistant containing at least one kind of aliphatic oxycarboxylic acid selected from a group consisting of lactate, malate and tartrate.SELECTED DRAWING: None
