STABILIZED TREATMENT METHOD OF NATURAL SOIL

摘要

PURPOSE:To manufacture a soil stabilizer by mixing A1-Fe base oxide mixture having pulverized iron oxide produced as a by-product in the steel manufacturing and red sludge produced as a by-product in the aluminum refining as materials with lime and improve the strength and viscoelasticity of treated soil by adding and mixing the stabilizer to natural soil, etc. CONSTITUTION:Soil stabilizer added with lime to A1-Fe base oxide mixture having aluminum oxide and iron oxide as the main ingredients is mixed with paving materials containing natural soil and crushed stone. The soil stabilizer constituted of composition adding lime to A1-Fe base oxide mixture containing titanium oxide having aluminum oxide and iron oxide as the main ingredients is mixed with paving materials containing natural soil. The ratio of titanium oxide in the soil stabilizer is ranged 0.5-2.0% by weight and ratio of titanium oxide is ranged 0.5-2.0% by weight.
