GROUT COMPOSITION
PROBLEM TO BE SOLVED: To provide a grout composition generating no bleeding while maintaining good flowability and good in strength development from low temperature to high temperature.SOLUTION: There is provided a grout composition containing (A) cement of 100 pts.mass, (B) a water reducing agent of 0.5 to 1.5 pts.mass, (C) hauyne having Blaine specific surface area of 2000 to 6000 cm/g of 0.3 to 2 pts.mass and (D) a limestone aggregate having particle side constitution of 25 to 40 mass% of particle diameter of 1.2 to 2.5 mm, 25 to 45 mass% of particle diameter of 0.6 to less than 1.2 mm, 20 to 35 mass% of particle diameter of 0.3 mm or more and less than 0.6 mm and 10 to 35 mass% of particle diameter of less than 0.3 mm of 90 to 110 pts.mass. There is provided a non-contractible grout composition preferably contains further a promoter and desirably contains (F) an expansive agent and (G) a foaming agent. There is provided a group composition preferably having water/cement ration (content mass ratio) of 32 to 40%.SELECTED DRAWING: None
【課題】良好な流動性を保持しながらブリーディングを発生させず、且つ低温から高温まで強度発現性が良好なグラウト組成物の提供。【解決手段】（Ａ）セメント１００質量部、（Ｂ）減水剤０．５〜１．５質量部、（Ｃ）ブレーン比表面積２０００〜６０００ｃｍ2／ｇであるアウイン０．３〜２質量部、および（Ｄ）粒径１．２〜２．５ｍｍ未満が２５〜４０質量％、粒径０．６〜１．２ｍｍ未満が２５〜４５質量％、粒径０．３ｍｍ以上０．６ｍｍ未満が２０〜３５質量％、粒径０．３ｍｍ未満が１０〜３５質量％の粒度構成である石灰石骨材９０〜１１０質量部を含有するグラウト組成物。好ましくは更に促進剤を含有し、その上（Ｆ）膨張剤及び（Ｇ）発泡剤を含有することが望ましい、無収縮性であるグラウト組成物。また、好ましくは、水／セメント比（含有質量比）が３２〜４０％であるグラウト組成物。【選択図】なし
