    PROBLEM TO BE SOLVED: To provide a cement dispersibility improvement aid which can sufficiently improve cement dispersibility in a cement composition and can reduce the amount of water-reducing agent, and provide a cement composition comprising such a cement dispersibility improvement aid.SOLUTION: A cement dispersibility improvement aid comprises a copolymer having a structural unit (I) derived from a specific unsaturated polyalkylene glycol ether monomer (a) and a structural unit (II) derived from hydroxyalkyl (meth) acrylate (b).SELECTED DRAWING: None

    【課題】セメント組成物におけるセメントの分散性を十分に向上させることができるとともに減水剤の量を低減できるセメント分散性向上助剤を提供する。また、そのようなセメント分散性向上助剤を含むセメント組成物を提供する。【解決手段】本発明のセメント分散性向上助剤は、特定の不飽和ポリアルキレングリコールエーテル系単量体（ａ）由来の構造単位（Ｉ）とヒドロキシアルキル（メタ）アクリレート（ｂ）由来の構造単位（ＩＩ）を有する共重合体を含む。【選択図】なし
