Methodology for Assessing the Probability of Corrosion in Concrete Structures on the Basis of Half-Cell Potential and Concrete Resistivity Measurements

Table 2

Dependence between concrete resistivity and corrosion probability [34].

Concrete resistivity 𝜌, kΩcm	Probability of corrosion
𝜌 < 5	Very high
5 < 𝜌 < 10	High
10 < 𝜌 < 20	Low to moderate
𝜌> 20	Low
