<p>A solidifying agent for improving soil is provided to reduce the cost required to perform firing, to avoid the generation of bad odor, the formation of hexavalent chrome and an increase in pH, and to allow prompt curing. A solidifying agent for improving soil is obtained by mixing 40-60 wt% of paper sludge fired at 800-1000 deg.C, 20 wt% of finely divided powder of furnace slag, 10-32 wt% of quick lime and 3-10 wt% of anhydrite, followed by homogenization. In a variant, a solidifying agent further comprises 5-20 wt% of fly ash in addition to 80-95 wt% of the above solidifying agent. Additionally, 0.1-10 wt% of an agglomerating agent is added to 5-20 wt% of fly ash.</p> |
