SHRINKAGE-REDUCING AGENT FOR HYDRAULIC MATERIAL
PROBLEM TO BE SOLVED: To provide a shrinkage reducing agent for a hydraulic material which exerts an excellent shrinkage-reducing ability with a small addition amount.SOLUTION: There is provided a shrinkage reducing agent for a hydraulic material which comprises a (poly)alkylene glycol-based block copolymer having a structure in which a polymer chain derived from a vinyl-based monomer component including an unsaturated anionic monomer and a terminal of a polymer chain (B) by polyalkylene glycol-based constitutional units are bonded via a binding site (X).
【課題】 少量の添加で優れた収縮低減性能を発揮する水硬性材料用の収縮低減剤を提供する。【解決手段】 不飽和アニオン系単量体を含むビニル系単量体成分由来の高分子鎖（Ａ）と（ポリ）アルキレングリコール系構成単位による高分子鎖（Ｂ）の末端とが結合部位（Ｘ）を介して結合した構造を有する（ポリ）アルキレングリコール系ブロック共重合体を含むことを特徴とする水硬性材料用収縮低減剤。【選択図】なし
