Methodology for Assessing the Probability of Corrosion in Concrete Structures on the Basis of Half-Cell Potential and Concrete Resistivity Measurements
Table 1
Dependence between potential and corrosion probability [8].
Potential E corr
Probability of corrosion
−350 mV
Greater than 90% probability that reinforcing steel corrosion is occurring in that area at the time of measurement
−350 mV −200 mV
Corrosion activity of the reinforcing steel in that area is uncertain
−200 mV
90% probability that no reinforcing steel corrosion is occurring in that area at the time of measurement (10% risk of corrosion)
