In order to examine soil stabilization with granulated slag, the masado and cohesive soils were mixed with slag and lime, and their chemical characteristics, unconfined compression strength, triaxial compression strength, and plate loading strength were determined. Furthermore the applicability of the granulated slag as a material for soil stabilization was discussed. Lime was found to be effective in pulling out the potential hydraulicity of granulated slag in a short time, raising the unconfined compression strength in 7 to 14 days, while decreasing the calcium concentration and pH value in the water soluble contents of the granulated slag. The mixture showed a better effect on the unconfined compression strength than the lime stabilization method. The similar effect was found in the triaxial compression strength, too. The increase in cohesion contributed to the increase in its strength. If this potential hydraulic granulated slag were scattered on the soft ground as a reclamational material, it would give 2 to 6 times more bearing power compared with the usual case of sand reclamation.
