PROBLEM TO BE SOLVED : To provide a solidification material for re-digging, which provides predetermined solidification intensity in an early stage after improvement work of soft ground and can thereafter sufficiently inhibit increase in the solidification intensity and sufficiently reduce the elution amount of hexavalent chromium from the improved ground; to provide a method for producing the solidification material; and to provide a method for improving ground using the solidification material.
SOLUTION : The solidification material for re-digging comprises : 10-40 mass% of a cement clinker with a hydraulic modulus (HM) of 2.20-2.35, a silica modulus (SM) of 2.50-2.90 and an iron modulus (IM) of 2.50-3.50, and a total chrome content of 30-70 mg/kg; and 60-90 mass% of an extending agent.
