摘要：

Under action of repeated freeze-thaw cycles, different changes of pore structure features has occurred in different varieties of concrete. In this study, the average pore size of concrete and total porosity was discussed especially with the trends. Based on this, the gas diffusion model and the chloride ion diffusion model in concrete was also discussed with the pore structure,which indicated that the freeze-thaw damage of concrete pore structure will have a greater impact to the durability of concrete, and so the life of concrete structures would be affected.
