ADDITIVE FOR GEOPOLYMER AND GEOPOLYMER HARDENING BODY

摘要

PROBLEM TO BE SOLVED: To provide an additive for geopolymer capable of improving workability (adjustment of setting time) of a geopolymer containing an active filler with CaO high content such as a blast furnace slag fine particles for example as an aluminosilicate source and providing a cured body excellent in further appearance without damaging flowability and strength development.SOLUTION: There is provided an additive for geopolymer consisting of a composition containing one or more kind of salt of aliphatic oxycarboxylic acid having hydroxyl value of 250 to 1500 mgKOH/g and acid value of 250 to 950 mgKOH/g with mass weighted average value of hydroxyl value/acid value of the aliphatic oxycarboxylic acid of 0.40 or more and less than 5.00.SELECTED DRAWING: None
