Corrosion of chloride contaminated reinforced concretes exposed to outdoor conditions and to six controlled environmental conditions was followed within a five year study. Corrosion was evaluated four times a year performing visual observations (rust, cracks, delamination) and electrochemical measurements from which corrosion rates were calculated. These latter values were converted in cumulative steel thickness loss versus cumulative time in order to propose a mathematical relation for simulating corrosion in the propagation phase. It was found that a mathematical power relation fitted the experimental data better than a linear relation. (C) 2016 Published by Elsevier Ltd.
