Abstract
This study presents an analysis of the chloride diffusion coefficient (D RCM ), obtained in electrically accelerated chloride migration tests. As demonstrated here, the obtained chloride diffusion coefficient does not represent the apparent one, as it is independent of chloride binding. This is accounted for the fact that the D RCM is calculated based on the average chloride penetration depth measured in concrete and binding at the position of the chloride penetration front is very limited. It is also demonstrated in this study that the apparent chloride diffusion coefficient in concrete is not constant within the sample, because it depends upon the local chloride concentrations.
