SOIL SOLIDIFICATION MATERIAL AND GROUND INJECTION METHOD USING THE SAME
To provide a suspension-type soil solidification material that can be used in combination with solution-type silica grout, features a short gelation time, can reduce CO2 emissions, causes no soil contamination, and exhibits superior durability, and a ground injection method that employs the soil solidification material and excels in preserving the environment.SOLUTION: A suspension-type soil solidification material, primarily composed of slag and cement, includes silica sol derived from metallic silicon. Either one of slag and cement, both, or their mixture has a Blaine specific surface area of 4000 cm2/g or more.SELECTED DRAWING: None
【課題】溶液型シリカグラウトと併用でき、ゲル化時間が短く、ＣＯ２の生成を削減でき、かつ、土壌汚染を生ずることがない耐久性に優れた懸濁型の地盤固結材、および、それを用いた環境保全性に優れた地盤注入工法を提供する。【解決手段】金属珪素から製造されたシリカゾルを含み、スラグおよびセメントを主成分とする懸濁型の地盤固結材である。スラグおよびセメントのうちのいずれか一方、その両方またはその混合物が、ブレーン比表面積４０００ｃｍ２／ｇ以上である。【選択図】なし
