摘要：
The essence of deterioration for cement-based materials is that the corrosive media enters into the internal parts of concrete through various transport channels to generate corrosive products, thus leading to the damage of structures.Therefore, the structural durability is closely rela-ted to the transport behavior of erosion media in cement-based materials. Existing concrete life prediction models and durability assessment stu-dies are mostly based on Fick and Darcy's laws. Starting from microstructure of cement-based materials and combining with the latest research results at domestic and foreign, this paper expounds the progress of numerical simulation research on the microstructure evolution and transport performance of cement-based materials. It has certain guiding significance for the study of promoting structural durability. © 2021, Materials Review Magazine. All right reserved.
