摘 要：To investigate the transport characteristics of chloride ions in cement-based materials,the Mori-Tanaka （M-T） prediction scheme of the effective diffusion coefficient in composites containing single-phase and multi-phase inclusions is systematically deduced based on the theory of composite mechanics and porous medium.The volume fraction,morphology and distribution of aggregates,as well as the interfacial transition zone （ITZ） are fully taken into consideration in this proposed model.The results show that the algorithm of M-T prediction scheme with high accuracy is relatively simple.
