Potentiodynamic polarization 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 | (mV versus SCE) | (mA⋅cm−2) × 10−4 | Corrosion rate (mmpy) × 10−3 | (mV versus SCE) | (mA⋅cm−2) × 10−5 | Corrosion rate (mmpy) × 10−4 |
| OPC | −397 | 6.9922 | 8.0082 | −301 | 2.1496 | 2.491 | PPC | −303 | 1.6902 | 1.9589 | −263 | 1.6902 | 1.9589 | PSC | −299 | 1.4448 | 1.674 | −258 | 1.4448 | 1.674 |
