GROUND IMPROVING MATERIAL AND GROUND IMPROVEMENT METHOD USING THE SAME
To provide: a ground improving material which is capable of reducing an elution volume of hexavalent chromium from a ground after improvement, and which has excellent strength development; and a ground improvement method using the ground improving material.SOLUTION: A ground improving material includes a cement-based solidification material and molybdenum. An amount of molybdenum is preferably 0.01-5.0 pts.mass relative to 100 pts.mass of the cement-based solidification material. The cement-based solidification material preferably includes plaster, and a ratio of the plaster in the cement-based solidification material is preferably 2-20 pts.mass in terms of anhydride. A ground improvement method is intended to obtain an improved ground by supplying the ground improving material including the cemented-based solidification material and molybdenum to the ground, followed by agitation and mixing.SELECTED DRAWING: None
【課題】改良後の地盤からの六価クロムの溶出量を抑制することができ、かつ、強度発現性に優れた地盤改良材、及び、それを用いた地盤改良方法を提供する。【解決手段】セメント系固化材及びモリブデンを含む地盤改良材。セメント系固化材１００質量部に対するモリブデンの量は、好ましくは０．０１～５．０質量部である。セメント系固化材は、好ましくは石膏を含み、かつ、セメント系固化材中の石膏の割合は、好ましくは無水物換算で２～２０質量部である。セメント系固化材及びモリブデンを含む地盤改良材を地盤に供給して、撹拌混合し、改良地盤を得る地盤改良方法。【選択図】なし
