ADDITIVE FOR RECYCLED AGGREGATE-CONTAINING CEMENT COMPOSITION
To provide an additive for a recycled aggregate-containing cement composition that can improve freeze-thaw resistance of concrete formed from a recycled aggregate-containing cement composition; also provide a cement composition that can give concrete that expresses excellent freeze-thaw resistance; and further provide a method for producing a cement composition that can give concrete that expresses excellent freeze-thaw resistance.SOLUTION: An additive for a recycled aggregate-containing cement composition has a copolymer (A) containing a structural unit represented by specific general formula (I) and a structural unit represented by specific general formula (II).SELECTED DRAWING: None
【課題】再生骨材を含むセメント組成物から形成されるコンクリートの凍結融解抵抗性を向上させ得る再生骨材含有セメント組成物用添加剤を提供する。また、優れた凍結融解抵抗性を発現するコンクリートを与え得るセメント組成物を提供する。さらに、優れた凍結融解抵抗性を発現するコンクリートを与え得るセメント組成物の製造方法を提供する。【解決手段】本発明の再生骨材含有セメント組成物用添加剤は、特定の一般式（Ｉ）で表される構造単位と特定の一般式（ＩＩ）で表される構造単位とを有する共重合体（Ａ）を含む。【選択図】なし
