Permeability coefficients of steel slag and traditional soils.
| | Material type | Permeability coefficient (cm/s) | Material type | Permeability coefficient (cm/s) |
| | Fine steel slag | 1 × 10−3∼8.9 × 10−3 | Pure gravel | >10−1 | | Coarse steel slag | 1 × 10−2∼9.2 × 10−2 | Mixture of pure sand and gravel | 10−3∼10−1 | | Gravel steel slag | 3 × 10−5∼5 × 10−2 | Mixture of silt, sand, and clay | 10−7∼10−5 | | Fly ash [9] | 10−5∼10−3 | Fine sand | 10−5∼10−3 | | Clay [26] | <10−7 | Steel slag-treated silt soil | 10−7∼10−3 |
