Abstract
Alternation of drying and wetting led to the worst corrosion of the engineering structures in marine environments. In this paper, the transport of chloride ions in concrete under loads and drying-wetting cycles was investigated. The influences of drying-wetting cycles, stress ratios and exposed ages of concrete on chloride ions transport in concrete were studied. The relationships between the coefficient of chloride ion diffusion and stress ratios of concrete under the loads and drying-wetting cycles were obtained. The relationship between the chloride ion concentration of concrete surface and exposed ages of concrete was studied. And the simplified transport model of chloride ions in concrete under loads and drying-wetting cycles was established, of which the validity was verified through the good agreement with the experimental data.
