HIGH WATER CONTENT DREDGING MUD SOLIDIFICATION STABILIZER AND IT'S IMPROVED SOIL PRODUCTION METHOD

摘要

A stabilizer for solidifying dredging mud is provided to ensure a large amount of natural resource by producing environment-friendly geomaterials from dredging mud having a high water content rapidly. A stabilizer for solidifying dredging mud having a high water content comprises 1-15wt% of a lime-based solidifying agent, 0.01-1 parts by weight of a polymeric flocculant, and 0.05-0.1 parts by weight of an inorganic hardener. A method for producing improved soil using the stabilizer includes a step of kneading 100 parts by weight, based on wet unit weight, of dredging mud with 1-15 parts by weight of the stabilizer. The solidifying agent comprises 25.30wt% of silica, 6.30wt% of alumina, 53.50wt% of lime, 1.57wt% of magnesia, 1.39wt% of hematite, 0.60wt% of potassium oxide, 0.50wt% of sodium oxide, and 10.40wt% of ignition loss.
