23 The degradation of reinforced concrete structures exposed to marine environment is largely 24 due to the transfer of chloride ions through the material. Indeed, the prediction of the 25 penetration of these ions in the concrete by the diffusion coefficient is a fundamental indicator 1 for the characterization of its durability. Actually, the tests simulating chloride diffusion in 2 saturated areas are developed at constant temperature. However, in reality the temperature 3 fluctuates with the seasons and diurnal variations. In order to simulate the coupled 4 temperature-diffusion of chloride in reinforced concrete structures in permanent contact with 5 the Mediterranean Sea, an experimental program was developed in the laboratory to assess the 6 migration coefficients of a pozzolanic concrete (CPZ10) and compared to ordinary concrete 7 referenced (OC). The tests of migration are made under electric field, at different 8 temperatures from 5 to 50oC (41 to 122°F). Also a study of the activation energy was made 9 and compared with the Arrhenius theory. The test results showed that the migration 10 coefficient of concrete increase with increasing temperature. The activation energy values of 11 natural pozzolan incorporated concretes were lower than ordinary concrete. 12 13
