摘要：

Reinforcement corrosion is one of the major durability problems that need to be solved in order to extend the service life of a structure. It is influenced, on one hand, by the concrete itself, sound or polluted (chlorinated or carbonated), and on the other hand, by the environmental conditions (controlled or outdoor). To explore the influence of temperature and humidity, electrochemical characterisations (potential, linear polarisation resistance and corrosion rate) were carried out on reinforced concrete prisms. A database of more than 3000 values has been delivered. The results enabled us to deduce that both parameters have influences on each other. Moreover, considering the four concretes, the corrosion order obtained in controlled conditions may be different from the one obtained in outdoor conditions.
