Corrosion behavior and evolution of steel reinforcement in simulated concrete pore solutions subjected to different corrosive ions (i.e., chloride, sulfate, chloride-sulfate, and simulate sea water) were investigated. Corrosion products induced with chloride and sulfate ions were also analyzed, respectively. The results show that the presence of sulfate ions in co-existence scenario of chloride-sulfate ions lead to a lower polarization resistance and a higher corrosion current density. The steel corrosion potential is correlated to the polarization resistance evolution as a power function relationship. Corrosion products induced by chloride and sulfate ions depicts a slight difference, mainly containing γ-FeOOH, α-FeOOH, Fe(OH)3, Fe2O3 and FeO.
