Mechanical Performance versus Corrosion Damage Indicators for Corroded Steel Reinforcing Bars
Table 8
Relation of CDI and PIs for practical corrosion conditions.
| | CDI | Nominal diameter: 16 mm |
| | Corrosion rate [µm/year] | Time in years to reach a mass loss of 5% for the following conditions | |
Poor concrete, low concrete cover, and/or cracked concrete |
Uncracked concrete or only small cracks together with a good concrete and a sufficient concrete cover | | Low: 1.16 | >150 | >150 | | High: 11.6 | <20 | <45 |
| | PIs | Nominal diameter: 16 mm |
| | Mass loss [%] | Mean value res. [—] | 5% quantile value res. [—] | Mean value res.dE [%] | 5% quantile value res.dE [MPa] | | 5.0 | 0.8 | 0.55 | 80% | 55% | | Mass loss [%] | Mean value res. [%] | 5% quantile value res. [%] | | 5.0 | 50 | 25 |
