A test specimen simulating a pier, which is a harbor structure with a series of reinforced concrete members from the atmospheric to the tidal zone, was fabricated and tested for exposure to seawater. The potential and current density of the reinforcing bars in each environmental category were observed to investigate the effect of tidal fluctuations on the corrosion of the reinforcing bars in the concrete. As a result, changes in the rebar potential and current density were observed in synchronization with tidal fluctuations. The formation of different macrocells was observed depending on the tidal level, and the macrocell characteristics changed with the lengthening of the exposure period.
