文摘

A meso-scale model is prosed to predict the effect of stress on diffusivity. The N-layered sphere model is used for predicting diffusion coefficient. Porosity is treated as the main parameter influencing the diffusivity in concrete. The quantitative relation between volumetric stress and diffusivity is given.
