Summary:PROBLEM TO BE SOLVED: To provide a grouting agent hardly reducing strength of foundation even when a freezing method is combined.SOLUTION: There is provided a grouting agent containing (a) polyalcohol and/or oxo acid ester and (b) sodium silicate, and further containing (c) acid and/or salt when at least oxo acid ester is not contained in the (a). The polyalcohol is preferably one or more selected from a group consisting of glycerol, ethylene glycol and trimethylolethane. The oxo acid ester is preferably one or more selected from a group consisting of ethylene carbonate, propylene carbonate and 3-phosphoglyceric acid.SELECTED DRAWING: None 【課題】凍結工法と併用した場合でも、地盤の強度が低下し難い地盤注入剤を提供すること。【解決手段】（ａ）多価アルコール及び／又はオキソ酸エステル類、及び（ｂ）ケイ酸ソーダを含み、少なくとも、前記（ａ）にオキソ酸エステル類が含まれない場合は、（ｃ）酸及び／又は塩類をさらに含む地盤注入剤。多価アルコールは、グリセリン、エチレングリコール、及びトリメチロールエタンから成る群から選択される１以上であることが好ましい。オキソ酸エステル類は、エチレンカーボネイト、プロピレンカーボネイト、及び３-ホスホグリセリン酸から成る群から選択される１以上であることが好ましい。【選択図】なし
