In this work, the corrosion behavior of carbon steels embedded in normal-performance cement pastes (NPCP) and ultra-high-performance cement pastes (UHPC) contaminated with seawater were studied. The results showed that the corrosion of the carbon steel propagated in NPCP due to the relatively low resistivity of the matrix. The initial high Cl/OH ratio induced the corrosion of steel after the cast of the seawater mixed UHPC, however it was suppressed immediately within the first few days due to the significant reduction of water, which inhibited the anodic reaction of the corrosion process. The insufficient oxygen supply did not dominate the corrosion process, since the phase conversion of the corrosion products could also sustain the cathodic reaction.
