AC-impedance parameters for the corrosion of rebar embedded in OPC, PPC, and PSC M40 grade concrete (90-day cured specimens).
| System | Various grades of concrete | M30 | M40 | (ohms⋅cm2) × 104 | (mA/cm2) × 10−4 | Corrosion rate (mmpy) × 10−3 | (ohms⋅cm2) × 106 | (mA/cm2) × 10−5 | Corrosion rate (mmpy) × 10−4 |
| OPC | 3.464 | 7.531 | 8.728 | 1.399 | 1.865 | 2.161 | PPC | 3.885 | 6.715 | 7.782 | 1.594 | 1.637 | 1.897 | PSC | 4.399 | 5.930 | 6.873 | 1.714 | 1.522 | 1.764 |
