Abstract: A multi-species and multi-phase model was used to simulate the chloride and moisture transports through non-carbonated, carbonated and partially carbonated concrete specimens. The reduction in porosity and permeability of the carbonated material were taken into account. The input data of the model are directly obtained by means of experiments (effective chloride diffusion coefficient) or by numerical inverse analysis (binding parameters, permeability, etc.). Experiments have been carried out to assess the chloride penetration profile through partially-carbonated concretes specimens exposed to absorption. The experimental profiles are compared to the simulated ones in order to validate the reliability of the approach.
