PROBLEM TO BE SOLVED: To provide a solidifying material that can increase the used amount of municipal waste incineration ash used as a raw material of cement clinker, can reduce the elution amount of hexavalent chromium from soil improved using a solidifying material containing cement clinker even if the total chromium content in the cement clinker is large, and has excellent strength development.SOLUTION: A solidifying material contains: a crushed product of cement clinker having a hydraulic modulus (H.M.) of 2.00-2.10, a free lime content of 0.1-1.0 mass%, a total chromium content of 200 ppm or more, and a ratio of water-soluble hexavalent chromium to the total chromium of 15 mass% or less; gypsum; and lime. The content of SOin the solidifying material is 3.5-15 mass%, and the content of the lime therein is 0.2-20 mass% (calculated as CaO).SELECTED DRAWING: None |
