英文摘要	In order to solve the problem of corrosion of reinforced concrete in saline soil environment, constant current accelerated corrosion test was carried out with current density of 182 μA/cm2,364 μA/cm2 and 546 μA/cm2. The corrosive properties of reinforced concrete were studied by polarization curve method (LPR), Cl- content analysis, EDS, etc. and the Copula function damage model and Cl- diffusion model were established. The research shows that the eutectic accelerated current corrosion efficiency of reinforced concrete is 364 μA/cm2,546 μA/cm2,182 μA/cm2 from high to low in the wet saline soil environment, and the constant current acceleration (no crack), The diffusion coefficient of Cl- is 1.115×10-12 m2/s. In the later stage (cracks appear), the larger the initial crack, the faster the reinforced concrete damage; the convective concrete constant current accelerated life value of 182 μA/cm2,364 μA/cm2 and 546 μA/cm2 are 700 h,350 h,175 h. © 2020, Materials Review Magazine.
