Based on numerical micro-structure model of cement paste, a lattice diffusion model is generated to study the influence of randomness on the chloride diffusion coefficient of capillary pore element.The results indicate that,compared with regular model, random model has longer diffusion distance, consequently, in order to get same simulation diffusion results, the formers diffusion coefficient should be adjusted a lttlte higher.
