<p><P>PROBLEM TO BE SOLVED: To provide a method for suppressing elution having a larger suppression effect on the elution of harmful substance. <P>SOLUTION: In the mixing process, a mixture for hydrothermal solidification made by mixing hydrated lime to sewage sludge incineration ash is prepared. In the forming process, the mixture for hydrothermal solidification is formed and a formed body is produced. The formed body is subjected to hydrothermal treatment, calcium silicate hydrate is produced and solidified and, as a result, hydrothermal solidificated material yielded as an apatite can be obtained. <P>COPYRIGHT: (C)2003,JPO</p> |
