Study on Permeability of Steel Slag and Steel Slag ...

Permeability coefficients of different types of steel slag and traditional soils are listed in Table 10. In order to clearly compare ranges of the permeability coefficient of steel slag and traditional soils, the histogram was drawn as shown in Figure 12. The permeability coefficients of the three kinds of pure steel slag, steel slag-treated silt soil, and traditional soils were compared.
