<p>PROBLEM TO BE SOLVED: To obtain a solidification material that can retain the viscosity increase at an equal level to the conventional product, when it is converted to slurry, shows strength increase for a long period of time and manifests excellent durability and is useful for solidification of the soil of high water content or of high organic substance content by using a specific cement. SOLUTION: This solidification material comprises (A) a cement containing calcium chloroaluminate or tricalcium aluminate prepared by using municipal waste incineration ash as a starting material (for example, municipal waste incineration ash is mixed with dry powder of sludge prepared by adding quicklime to seashells and sludge, other domestic or industrial waste, further calcite as a starting substance for cement, clay, iron powder and the like are mixed to adjust the components and the mixture is fired at 1,000-1,400 deg.C, and crushed while plaster is added), in addition, when necessary, (B) plaster and (C) a mixed cement. In a preferred embodiment, this material contains the components A, B and C in amounts of 5-40 wt.%, 5-30 wt.% and 30-90 wt.%, respectively.</p> |
