<p>PROBLEM TO BE SOLVED: To inexpensively and surely harden soft soil having a high water content by using steel making slag/molten iron preliminary treatment slag, etc. SOLUTION: Soil containing water is mixed with 15-65wt.% based on the total dry weight after blending of steel making slag/molten iron preliminary treatment slag ground to have the maximum particle diameter within the range of 3-50mm, 0.5-5wt.% of fine powder of blast-furnace slag, 0.5-10wt.% of gypsum, 1-10wt.% of coal ash and 1-10wt.% of an alumina-based substance and hardened so that the soil is hardened so that soil can be hardened by using mainly industrial waste without using an expensive cement, lime, an alumina containing clay mineral.</p> |
