ABSTRACT
The mechanisms of corrosion of steel in concrete are discussed in Section 4.3. In this chapter, they will be reviewed while considering how cathodic protection (CP) can be used to control corrosion. We review the electrochemical potentials and the corrosion currents of corroding and ‘cathodically’ protected steel in concrete and then review the criteria for achieving CP and how these are reflected in the major standards for CP of steel in concrete currently available.
