ADDITIVE FOR HYDRAULIC CEMENT COMPOSITIONS
PROBLEM TO BE SOLVED: To provide an additive for hydraulic cement compositions, wherein: an aqueous solution comprising the additive has high stability and has high solubility with a conventional additive for hydraulic cement compositions; and a resultant cured body has excellent freeze-thaw resistance.SOLUTION: An organic amine salt of a specific fatty alcohol phosphate is used which is obtained by having the specific fatty alcohol phosphate neutralized by a specific organic amine, as an additive for hydraulic cement compositions.SELECTED DRAWING: None
【課題】それ自体の水溶液の安定性が高く、また既存の水硬性セメント組成物用添加剤との溶解性も高く、結果として得られる硬化体が凍結融解抵抗性に優れたものとなる水硬性セメント組成物用添加剤を提供する。【解決手段】水硬性セメント組成物用添加剤として、特定の脂肪族アルコールリン酸エステルを特定の有機アミンで中和した特定の脂肪族アルコールリン酸エステルの有機アミン塩を用いた。【選択図】なし
