<p><P>PROBLEM TO BE SOLVED: To provide an offensive smell generation suppressing solidifying mate rial capable of suppressing the generation of an ammonia smell when solidifying sludge, and ensuring sufficient strength in early stages. <P>SOLUTION: The offensive smell generation suppressing solidifying material comprises magnesium oxide. Various gypsums, reaction accelerators and phosphates may be added in order to enhance initial strength. Further, a retarder may be added. By adding the powdery or slurry-like solidifying material to soil to mix the same therewith, sufficient strength is obtained suppressing the generation of an offensive smell. <P>COPYRIGHT: (C)2003,JPO</p> |
