GROUTING MATERIAL AND SOIL IMPROVEMENT METHOD
To provide a grouting material that achieves improved soil with high durability, without the need for adding colloidal silicas.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 flock of the gelled body has a porod volume of 4000 nm3 or less, the floc having a radius of gyration of 9.5 nm or less.SELECTED DRAWING: None
【課題】コロイダルシリカを添加しなくても、耐久性の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時間後のゲル状体を構成する凝集粒子のポロド体積が４０００ｎｍ３以下であり、前記凝集粒子の回転半径が９．５ｎｍ以下である地盤注入材である。【選択図】なし
