Abstract The corrosion behavior of reinforced steel with different surface states in simulated pore solution with gradual augment of Cl- was investigated by using electrochemical measurements, scanning electron microscopy with energy dispersive SEM/EDS and XRD. The variation of corrosion potential and corrosion current density of the reinforced steel with corrosion time was obtained, and the morphology and structure of corrosion products formed on the sample were analyzed. The results showed that the reinforced steel with different surfaces state had different corrosion characterizations; the corrosion process of reinforced steel might include three steps, i.e., the formation of passive film, the aggression of Cl- and the calcium deposition. It is more easy to happen corrosion for reinforced steel with oxide layer.
