GROUTING MATERIAL AND SOIL IMPROVEMENT METHOD
To provide a grouting material that achieves improved soil with high durability, even under contact with water.SOLUTION: A grouting material includes the combination of a basis containing water glass and a curing agent. The basis and the curing agent are mixed and gelled. One hour after, the gelled body is subjected to FTIR/ATR measurement, in which the value of the strength around 3099 cm-1 divided by the strength around 3345 cm-1 is 0.55 or less.SELECTED DRAWING: None
【課題】水接触下においても耐久性が良好な改良地盤とすることが可能な地盤注入材を提供する。【解決手段】水ガラスを含む主剤と硬化剤との組み合わせからなる地盤注入材であって、前記主剤と前記硬化剤とを混合し、ゲル化してから１時間後のゲル状体におけるＦＴＩＲ／ＡＴＲ測定において、３０９９ｃｍ－１付近の強度を３３４５ｃｍ－１付近の強度で除した値が０．５５以下である地盤注入材である。【選択図】なし
