英文摘要	In view of the short service life of reinforced concrete structures in the western salty soil environment, a composite solution composed of sodium chloride and magnesium sulfate was set up according to the salty soil environment to prepare reinforced concrete specimens of different strength levels. The specimens were placed in the solution for long-term immersion. Long-term follow-up study was conducted on the steel in concrete through CS350 electrochemical workstation to explore the corrosion law of reinforced concrete during multi-factor corrosion. Based on the observed data, a random process model in Gamma was established and the residual life was predicted. The results show that the corrosion resistance of reinforced concrete increases with the increase of strength grade. The Gamma random process can be used to describe the corrosion trajectory of steel in concrete effectively, and the residual life of reinforced concrete predicted by this method is feasible. © 2020, Central South University Press.
