SOIL IMPROVEMENT MATERIAL AND SOIL IMPROVEMENT METHOD
To provide a soil improvement material that can maintain an elution amount of hexavalent chromium at a sufficiently low level over a long period of time from the initial stage of material age even though an object to be soil-improved is a soil type having a relatively high chromium content in a cement clinker and being easy to allow hexavalent chromium to be eluted.SOLUTION: The soil improvement material includes a cement clinker, blast furnace slag, calcium sulfite and gypsum.SELECTED DRAWING: None
【課題】セメントクリンカーのクロム含有率が比較的高く且つ六価クロムが溶出しやすい土種が地盤改良対象であっても、六価クロムの溶出量を材齢初期から長期にわたって十分に低いレベルに維持することができる地盤改良材を提供する。【解決手段】本発明に係る地盤改良材は、セメントクリンカーと、高炉スラグと、亜硫酸カルシウムと、石膏とを含む。【選択図】なし
