CONSOLIDATING MATERIAL FOR GROUTING AND MANUFACTURING METHOD THEREFOR
To provide a consolidating material for grouting easily being manufactured while suppressing generation of partial gel even though SiOcontent is high such as 11 mass% or more, of which gelling time keeps long, and good in penetrability to soil.SOLUTION: There is provided a consolidating material for grouting containing sodium silicate, magnesium hydroxide and an acid component, (1) the consolidating material for grouting has SiOcontent of 11 mass% or more, (2) average particle diameter of a solid component containing Si is 0.80 nm or less, and (3) gelling time is 1 hr. or longer.SELECTED DRAWING: None
【課題】SiO2含有量が11質量%以上と多いにもかかわらず、部分ゲルの発生が抑制されていて調製が容易であり、ゲル化時間が長く確保されており、しかも地盤への浸透性が良好な地盤注入用固結材を提供する。【解決手段】珪酸ソーダ、水酸化マグネシウム及び酸成分を含有する地盤注入用固結材であって、(1)前記地盤注入用固結材は、SiO2濃度が11質量%以上であり、(2)Siを含有する固形分の平均粒子径が0.80nm以下であり、(3)ゲル化時間が1時間以上である、ことを特徴とする地盤注入用固結材。【選択図】なし
