HYDRAULIC COMPOSITION, CURED MATTER, AND MANUFACTURING METHOD OF HYDRAULIC COMPOSITION
To provide a hydraulic composition capable of producing a cured matter having sufficient strength and low water absorptivity.SOLUTION: A hydraulic composition comprises: (A) cement; (B) polyalcohol being an optional component; (C) polyvalent isocyanate; and (D) a urethane compound including residue of the polyalcohol and residue of the polyvalent isocyanate. When the hydraulic composition comprises the (B) component, the (B) component includes the polyalcohol included in the (D) component as the residue and the (C) component includes the polyvalent isocyanate included in the (D) component as the residue, and the total amount of the (B) to (D) components satisfies at least one of the following conditions (1) and (2): (1) being 18 pts.mass or lower relative to 100 pts.mass of the (A) component; and (2) being 4.15 mass% or lower relative to 100 mass% of the total amount of the hydraulic composition.SELECTED DRAWING: None
【課題】十分な強度を有し、低い吸水性を有する硬化物を得ることができる水硬性組成物を提供すること。【解決手段】水硬性組成物であって、（Ａ）セメント、（Ｂ）任意成分である多価アルコール、（Ｃ）多価イソシアネート、及び（Ｄ）多価アルコールの残基及び多価イソシアネートの残基を含むウレタン化合物を含み、水硬性組成物が（Ｂ）成分を含む場合、（Ｂ）成分は（Ｄ）成分に残基として含まれる多価アルコールを含み、（Ｃ）成分は（Ｄ）成分に残基として含まれる多価イソシアネートを含み、（Ｂ）～（Ｄ）成分の合計量が、以下の条件（１）及び（２）の少なくとも一方を満たす、水硬性組成物。（１）前記（Ａ）成分１００質量部に対して１８質量部以下である。（２）水硬性組成物の総量１００質量％に対して４．１５質量％以下である。【選択図】なし
