| Abstract: | For the service structures under acidic environment,the structural safety will decline due to the corrosion damage by the corrosive agents in the environment.In this paper,research of the accelerated corrosion test of structural bending members under acidic environment is done.Based on the test result,the basic corrosion mechanism of the structures is proved,the corrosion effects by different acidic agents and the basic corrosion damage procedures of the corroded structures are analysed,the variability of the reinforcement corrosion current density is estimated.And basic dates for the establishment of the corrosion rate model are given, which is important for further structural durability analysis of the corroded structures. |
