GROUND INJECTION MATERIAL AND GROUND IMPROVEMENT METHOD
To provide ground injection material, a manufacturing method thereof, and a ground improvement method thereby allowing a same ground improvement effect to be done even when reducing used amount of colloidal silica less than previous amount thereof.SOLUTION: Ground injection material, a manufacturing method thereof, and a ground improvement method using the ground injection material comprise a ground injection material mixed with colloidal solution, water glass solution, and acid reaction agents or acid silica sol to show acid or neutral, wherein alkaline silica solution produced by mixing colloidal solution and water glass solution is opaquely suspended at 25°C.SELECTED DRAWING: Figure 11
【課題】コロイダルシリカの使用量を従来より低減しても、同等の地盤改良効果を奏し得る地盤注入材、その製造方法、および、これを用いた地盤改良工法を提供する。【解決手段】コロイド溶液と、水ガラス溶液と、酸性反応剤または酸性シリカゾルとが混合されてなり、酸性ないし中性を呈する地盤注入材であって、コロイド溶液と水ガラス溶液とを混合してなるアルカリ性シリカ溶液が、２５℃において白濁を呈する地盤注入材、その製造方法、および、この地盤注入材を用いた地盤改良工法である。【選択図】図１１
