<p><P>PROBLEM TO BE SOLVED: To provide a filled material for a caisson, using soil having contaminated soil subjected to stabilization treatment as the raw material. <P>SOLUTION: The filled material for a caisson is produced so that the elution amount of heavy metals is suppressed by adding a solidifying material to contaminated soil, further, a granulating material is added to the soil to control the content of fine particle components with a particle size of≤75μm to≤5.0 wt.%, and further, smelting slag is added thereto to control specific gravity to≥2.5 and packing density to≥1.6 g/cm<SP>3</SP>. Preferably, the elution amount of lead is reduced to≤0.01 mg/L, the elution amount of mercury is reduced to≤0.0005 mg/L, and the elution amount of boron is reduced to≤1.0 mg/L. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
