GROUT MATERIAL, AND GROUT INJECTION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a gout material capable of reducing volume shrinkage caused by pressure dehydration at the injection time, which is a problem of a conventional grout material containing cements and bentonite.SOLUTION: A phosphoric acid alkali metal salt for reducing volume shrinkage caused by pressure dehydration is added as much as 1.3 kg or more and 6.0 kg or less per 1 minto a gout material for enhancing a foundation by being injected into the foundation, which is a grout material containing cements and bentonite.
【課題】セメント類とベントナイトを含有する従来のグラウト材の問題点である注入時の圧力脱水による体積収縮の低減を図ることのできるグラウト材を提供する。【解決手段】地盤に注入されて地盤を強化するグラウト材であって、セメント類とベントナイトとを含有するグラウト材において、グラウト材の圧力脱水による体積収縮を低減するリン酸アルカリ金属塩を1m3あたり1.3kg以上6.0kg以下添加する。
