Furthermore, chloride ion diffusion coefficient has exponent relation to surface water absorption with higher correlation coefficient. In addition, both impermeability and resistance to sulfate attack were linearly associated with surface sorptivity, and both correlation coefficients were not less than 0.9. Results obtained also showed that only surface water absorption related to the performance of concrete including permeability, sulfate attack, and chloride ion diffusion. As a result, both of surface sorptivity and internal sorptivity have no clear relationship with compressive strength. After 28-days curing, compressive strength, permeability, sulfate attack, and chloride ion diffusion of concrete samples were investigated. SEM photos also showed that different curing conditions caused different microstructure. Concrete specimens of different water absorption were prepared through different curing conditions, and results indicated that curing condition can significantly affect the surface water absorption. A detailed analysis is also presented in order to establish useful relationship between them. This paper presents an experimental study of the influence of water absorption on the durability of concrete materials. Environment has significant effects on the water absorption of concrete materials.
