GROUND CONSOLIDATION MATERIAL AND GROUND IMPROVEMENT METHOD
To provide a ground consolidation material which enables formation of a large-sized high-strength consolidated body by injecting a suspension containing water glass and a fine particle slag as active ingredients into the ground.SOLUTION: A ground consolidation material consolidates the ground by injecting a suspension containing water glass having a molar ratio of 1.5-2.8 and a fine particle slag having a specific surface area of 4,000 cm2/g to 20,000 cm2/g as active ingredients into the ground, in which flowability of the suspension is obtained by processes of (1) holding penetrability, (2) rapidly lowering the penetrability and setting a pseudoplastic state, (3) holding the pseudoplastic state, and (4) losing the pseudoplasticity and setting a consolidated state. Alternately, the flowability of the suspension exhibits primary gelation of exhibiting pseudoplasticity after the penetrability, and secondary gelation of causing solidification through the pseudoplasticity. Alternately, the flowability of the suspension is composed of flowability exhibiting penetrability, and flowability to the solidified state from exhibition of the pseudoplasticity.SELECTED DRAWING: Figure 10
【課題】水ガラスと微粒子スラグを有効成分とする懸濁液を地盤に注入して、大径の高強度固結体を形成させる地盤固結剤を提供する。【解決手段】モル比が1.5～2.8の範囲にある水ガラスと比表面積が4000cm２/ｇ～20000cm２/ｇの微粒子スラグを有効成分とする懸濁液を地盤に注入して地盤を固結する地盤固結材であって、該懸濁液の流動性は、（１）浸透性を保持する過程と、（２）その後急激に浸透性が低下して疑塑性状態になる過程と、（３）その後疑塑性状態を保持する過程と、（４）疑塑性が失われて固結状態になる過程とからなる。あるいは、該懸濁液の流動性は、浸透性を経て疑塑性を呈する１次ゲル化と、疑塑性を経て固化する２次ゲル化とを呈する。あるいは、該懸濁液の流動性は、浸透性を呈する流動性と、その後の疑塑性を呈して固化状態に至るまでの流動性とからなる。【選択図】図１０
