ULTRA-HIGH STRENGTH CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide an ultra-high strength cement composition that contains water, cement and silica fumes and can exhibit sufficient flowability even with a small amount of water.SOLUTION: An ultra-high strength cement composition contains: a polycarboxylic acid based copolymer (P) that comprises a structural unit (I) derived from an unsaturated polyalkylene glycol based monomer (a) represented by the general formula (1) and a structural unit (II) derived from an unsaturated carboxylic acid based monomer (b) represented by the general formula (2); an oxyalkylene ether based compound (Q) represented by the general formula (3); water; cement; and silica fumes.
【課題】水、セメント、およびシリカヒュームを含む超高強度セメント組成物であって、少量の水でも十分な流動性が発現できる超高強度セメント組成物を提供する。【解決手段】本発明の超高強度セメント組成物は、一般式（１）で表される不飽和ポリアルキレングリコール系単量体（ａ）由来の構造単位（Ｉ）と一般式（２）で表される不飽和カルボン酸系単量体（ｂ）由来の構造単位（ＩＩ）とを含むポリカルボン酸系共重合体（Ｐ）、一般式（３）で表されるオキシアルキレンエーテル系化合物（Ｑ）、水、セメント、およびシリカヒュームを含む。【選択図】図１
