The permeability of converter slag, replacing material of sand mat on improving soft clay foundation, was evaluated in the laboratory. The effects of grain size, flow water time and aging were investigated using sea and fresh water. In the case of converter slag submerged with fresh water, the coefficients of permeability in A and B samples less than 10 mm grain sizes were measured as $6.52 imes10^{-2}cm; per; sec; and; 5.99 imes10^{-1}/cm$ per sec respectively, while they were $1.88 imes10^{-2}/cm; per; sec,; 3.86 imes10^{-1}/cm$ per sec respectively under sea water condition. Also, the condition of turbulent flow may exit and was experimentally identified from the relationship between hydraulic gradient and seepage velocity. After 100 days under sea water condition, the coefficients of permeability of A and B samples decreased ten times than initial values. The reduction of permeability coefficient was considered to result from the filling of voids in high-calcium quicklime(CaO).
