PREMIX GROUT COMPOSITION
PROBLEM TO BE SOLVED: To provide a premix grout composition that has dry shrinkage of 800 μ or less for the long term, shows excellent flowability, and prevents material separation.SOLUTION: The premix grout composition comprises cement, expansion material, aggregate, cement dispersant and viscosity improver, with the aggregate of a specific particle size. The content ratio (a/P) of the aggregate to the mass of binding material is set to a specific ratio. Further, it is suitable that the content of cement, the content of expansion material, the content of cement dispersant and the content of viscosity improver are set to a specific content, respectively.
【課題】長期における乾燥収縮率が８００μ以下であり、流動性に優れ、材料分離が起こり難いプレミックスグラウト組成物を提供すること。【手段】セメント、膨張材、骨材、セメント分散剤及び増粘剤を含有し、骨材が特定粒度の骨材とする。また、結合材の質量に対する骨材の含有比率（ａ／Ｐ）を特定の比率とする。更に、セメントの含有率、膨張材の含有率、セメント分散剤の含有率及び増粘剤の含有率を、それぞれ特定の含有率とすると好適である。【選択図】なし
