REDUCTION MATERIAL, CEMENT COMPOSITION, SOIL IMPROVER AND IMPROVED SOIL
To provide a reduction material that can sufficiently reduce the amount of elution of hexavalent chromium while reducing the amount of use of sulfide, and a cement composition, a soil improver and an improved soil that can sufficiently reduce the amount of elution of hexavalent chromium while reducing the amount of use of sulfide.SOLUTION: A reduction material has sulfite and sulfide. A cement composition and a soil improver each contain the reduction material. An improved soil contains a soil to be improved and the soil improver.SELECTED DRAWING: None
【課題】硫化物の使用量を低減しつつ、六価クロムの溶出量を十分に抑制することが可能な還元材を提供すること。また、硫化物の使用量を低減しつつ、六価クロムの溶出量を十分に抑制することが可能なセメント組成物、地盤改良材及び地盤改良土を提供すること。【解決手段】還元材は、亜硫酸塩と硫化物とを含む。セメント組成物及び地盤改良材はこの還元材を含む。地盤改良土は、地盤改良対象土と地盤改良材とを含む。【選択図】なし
