ADDITIVE FOR GEOPOLYMER AND GEOPOLYMER HARDENING BODY
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
【課題】アルミノシリケート源として例えば高炉スラグ微粉末等のCaO高含有量の活性フィラーを含むジオポリマーの作業性(凝結時間の調整)を改善できるとともに、流動性と強度発現性を損なうことなく、さらに外観に優れる硬化体を得られるジオポリマー用添加剤を提供すること。【解決手段】水酸基価が250〜1500mgKOH/g、かつ酸価が250〜950mgKOH/gである1種以上の脂肪族オキシカルボン酸の塩を含む組成物からなるジオポリマー用添加剤であって、前記脂肪族オキシカルボン酸の水酸基価/酸価の質量加重平均値が0.40以上5.00未満である、ジオポリマー用添加剤。【選択図】なし
