Abstract: Water molecules are transported inside the cement-based materials through all levels of pores, bringing corroding ions into the material, which have an adverse impact on the properties of the materials. In order to deeply understand the pore structure and water absorption performance of cement-based materials, the relevant literature reviews on mechanical theory research were conducted in this paper. The classification methods of the pore of cement-based materials were compared and the multiple technologies on characterization of pore structure were analyzed, as well as their applications were presented. In addition, it emphasized the permeability theory of cement-based materials and the relationship between capillary water absorption mechanics with pore structure parameters. Meanwhile, the paper reviewed the present scholars’ studies in terms of nano-scale pore simulation of cement-based materials based on molecular dynamics theory. Finally, it summarized the relationship between pore structure and water absorption performance and looked forward the prospect of research in this field.

Key words: cement-based material, pore structure, water absorption performance, mechanics, action mechanism, microscopic characterization
