SOIL INJECTION MATERIAL
PROBLEM TO BE SOLVED: To provide an injection material good in permeability to the soil and high in initial strength development property as it is capable of enhancing dispersibility even when a large amount of fine particles easy to aggregate in a slurry is contained.SOLUTION: There is provided a soil injection material containing (A) Portland cement, (B) a slag powder, (C) gypsum (including gypsum in cement), (D) a water soluble sulfate and (E) a dispersant, and having weight ratio of the component (C) in the component (A) and the component (C), ((C)/((A)+(C))) of 0.1 to 0.3 in terms of SO, a maximum particle diameter of the total inorganic particles other than the component (D) and the component (E) of 14 μm or less and particles having a particle diameter of 1.0 μm or less of 4 to 40 vol.%.SELECTED DRAWING: None
【課題】スラリー中において凝集し易い微粒子が多く含まれても分散性を高めることが出来るため地盤への浸透性が良好で、かつ初期強度発現性の高い注入材を提供すること。【解決手段】（Ａ）ポルトランドセメント、（Ｂ）スラグ粉末、（Ｃ）石膏（セメント中の石膏を含む）、（Ｄ）水溶性硫酸塩、及び（Ｅ）分散剤を含有し、成分（Ａ）及び成分（Ｃ）中の成分（Ｃ）の重量比（（Ｃ）／（（Ａ）＋（Ｃ）））がＳＯ3換算で０．１〜０．３であり、かつ成分（Ｄ）及び成分（Ｅ）以外の全無機粒子の最大粒径が１４μｍ以下、粒径１．０μｍ以下の粒子が４〜４０体積％であることを特徴とする地盤注入材。【選択図】なし
