Zusammenfassung:	To provide an admixture for a water-hardening composition that is excellent in the effect of reducing the drying shrinkage of a cured product to be obtained and can impart excellent resistance against material separation.SOLUTION: An admixture for a water-hardening composition comprising component A, which is a water-soluble vinyl copolymer, and components B and C, which are specific polyoxyalkylene compounds. And, a water-hardening composition added with the admixture for water-hardening composition.SELECTED DRAWING: None 【課題】得られる硬化体の乾燥収縮を低減する効果に優れると共に、優れた材料分離抵抗性を付与することが可能な水硬性組成物用混和剤を提供する。【解決手段】水溶性ビニル共重合体であるＡ成分と、特定のポリオキシアルキレン化合物であるＢ成分とＣ成分とを含有する水硬性組成物用混和剤及びその水硬性組成物用混和剤が添加された水硬性組成物。【選択図】なし
