The determination of the effective diffusivity of cement-based materials is a point of major importance to control service life of concrete structures. In this contribution, a multiscale model for cement-based materials focusing on the prediction of effective diffusivity is developed, treating cement-based materials as hierarchically organized material separated by three length scales. The comparison with experimental data taken from the literature reveals the non-negligible contribution of gel-pore.
