HIGH FLUIDITY RETENTION TYPE LOW HEAT GENERATION GROUT COMPOSITION
PROBLEM TO BE SOLVED: To provide a low heat generation grout composition retaining fillable high fluidity for several hours or more and excellent material separation resistance.SOLUTION: There is provided a high fluidity retention type low heat generation grout position containing a binding material containing Portland cement and pozzolan, an aggregate, a thickener, and a dispersant with the Portland cement of 40 to 65 pts.mass, silica fume and/or metakaolin of 3 to 15 pts.mass, and pozzolan other than silica fume and metakaolin of 20 to 50 pts.mass based on 100 pts.mass of the binding material, a polycarboxylic acid-based dispersant of 0.2 to 1.2 pts.mass and a melamine sulphonic acid-based dispersant of 1 to 6 pts.mass based on 100 pts.mass of the Portland cement.SELECTED DRAWING: None
【課題】充填可能な高い流動性を数時間以上保持し、材料分離抵抗性に優れた低発熱性のグラウト組成物の提供。【解決手段】ポルトランドセメント及びポゾランを含む結合材と、骨材と、増粘剤と、分散剤とを含有するグラウト組成物であって、結合材１００質量部に対しポルトランドセメントを４０〜６５質量部、シリカフューム及び／又はメタカオリンを３〜１５質量部、シリカフューム及びメタカオリン以外のポゾランを２０〜５０質量部含有し、ポルトランドセメント１００質量部に対しポリカルボン酸系分散剤を０．２〜１．２質量部、メラミンスルホン酸系分散剤を１〜６質量部含有することを特徴とする高流動性保持型低発熱性グラウト組成物。【選択図】なし
