摘要：

The motivation of this contribution is to apply computational diffusion homogenization to the microscale and mesoscale of concrete sequentially, while taking into account both physical and chemical bindings. The effective diffusivity of cement paste obtained by homogenization at the microscale is considered as the input for diffusion homogenization at the mesoscale, thereby establishing the link between three length scales of concrete. Comparisons between numerical results of each step of the diffusion homogenization and experimental data from the literature are reported and discussed.
