CORROSION OF STEEL IN CRACKED CONCRETE: EXPERIMENTAL INVESTIGATION
The polarization response of a steel bar with an established macrocell is presented.A simple circuit-based model, which allows for predicting the polarization response of the macrocell is described. The results indicate that there is a spatial variation in the potential relative to the crack. It is shown that the applied current is primarily confined to the active steel located near the crack.
