PREMIX COMPOSITION USED FOR COMPACTION MATERIAL FOR GROUND REINFORCEMENT, COMPACTION MATERIAL FOR GROUND REINFORCEMENT, PRODUCTION METHOD OF THE SAME, AND GROUND REINFORCING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a premix composition used for a compaction material for ground reinforcement, the compaction material and a ground reinforcing method using the same which can keep peripheral ground neutral even when pressed into neutral ground, which can be pressed into a ground and which is quickly consolidated after pressed in.SOLUTION: A premix composition includes at least gypsum and an aggregate and is used for a compaction material for ground reinforcement. The compaction material includes at least gypsum, an aggregate, and water, in which a pH value after completion of strength development is 5.8 to 8.6, and in which the strength development is completed within 24 hours after completion of mixing the gypsum, the aggregate, and the water. A ground reinforcing method comprises: pressing the compaction material into a drilled hole formed in the ground by using a static press-in compaction construction method, to form consolidated lump; and compressing peripheral ground to increase density of the ground.SELECTED DRAWING: Figure 3
【課題】 中性の地盤に圧入しても周辺地盤を中性に維持できるとともに、地盤への圧入が可能で、且つ、圧入後に速やかに固結する地盤強化用締固め材に用いるプレミックス組成物、当該締固め材、及びそれを用いた地盤強化方法を提供する。【解決手段】 少なくとも石膏と骨材を含む、地盤強化用締固め材に用いるプレミックス組成物である。また、少なくとも石膏、骨材及び水を含む地盤強化用締固め材であって、強度発現完了後のｐＨが５．８以上８．６以下であり、強度発現を前記石膏、骨材及び水の混合完了時から２４時間以内に完了する前記締固め材である。また、前記の締固め材を静的圧入締固め工法等を用いて地盤に形成した削孔に圧入して固結塊を造成し、周囲地盤を圧縮して地盤の密度を増大させる地盤強化方法である。【選択図】 図３
