AB  - We present in this work a modeling of calcium leaching in concrete by taking into account the influence of the presence of aggregate. The modeling consists of the derivation of the microscopic equation governing the average concentration field in the equivalent medium as well as the determination of the macroscopic transport parameters. The homogenization method allows to estimate the diffusion and tortuosity tensor to be introduced in the macroscopic formulation of mass conservation law. These estimates depend on the morphological parameters of the microstructure which represent the geometry of the domain occupied by the phase in which the diffusion process…
