Figure 16: Effect of the concrete resistivity and the concentration of chlorides ions on the corrosion rate.

The evolution of the residual section of reinforcement for different resistivity values is shown in Figs. 17 for moderate and extreme environment. It is noticed that the resistivity of concrete has an handicapping effect on the propagation of
