Prédiction de la pénétration des chlorures dans les structures en béton armé

Abstract

This paper deals with the prediction of reinforcement corrosion development due to chloride ions penetration. The service life prediction based on calculation of the apparent diffusion coefficient must be upgraded by taking into account the real service conditions of the structure. As a result, the loading state and loading level of the structure induce a macroscopic cracking and a microscopic damage, furthermore the geometry modifies the micro-environment concrete homogeneity. The relative significance of these parameters is quantified.
