time for corrosion initiation, which is equal to 144.16 years. The structure was ana-
lyzed considering four different water/cement ratios which are equal to 0.40, 0.50,
0.60, and 0.70.
Figures 5.12 and 5.13 illustrate the variation of the resistant structural load along
time considering uniform and pitting rebar corrosion, respectively, and the four dif-
ferent water/cement ratios mentioned above. In these figures, only the propagation
period of corrosion is considered.
