COUNTERMEASURE MATERIAL FOR POLLUTION BY HEAVY METALS, ETC., AND COUNTERMEASURE CONSTRUCTION METHOD FOR POLLUTION BY HEAVY METALS, ETC., USING THE POLLUTION COUNTERMEASURE MATERIAL

摘要

To provide a countermeasure material for pollution by heavy metals, etc., capable of insolubilization of heavy metals, etc., in a soil, which is an acidic soil and a soil being acidic for an extended period of time, solidifying the soil and improving hardness, maintaining the pH of the modified soil in neutral region, and a countermeasure construction method for pollution by heavy metals, etc., using the countermeasure material.SOLUTION: The countermeasure material for pollution by heavy metals, etc., is a countermeasure material for pollution by solidification and insolubilization of heavy metals, etc., in an acidic soil and a soil being acidic for an extended period of time, and contains a dolomite-based compound and a component which contains an acidic sulfate and a polymeric material as essential and necessary components, wherein the acidic sulfate is involved at a rate of 1-20 mass% to the total amount of the dolomite-based compound and the acidic sulfate, the polymeric material is involved at an external rate of 0.1-10 mass% to the total amount of the dolomite-based compound and the acidic sulfate, and MgO is involved at a rate of 6-12 mass% to the pollution countermeasure material such as heavy metals, etc..SELECTED DRAWING: None
