| Abstract;Reinforced concrete beams of several types were placed in the splash zone at three locations on the Sea of Japan, the Seto Inland Sea and the Pacific Ocean. The changes in the beams over time, including the corrosion of the reinforcing steel, were investigated using electrochemical methods. Although corrosion of the reinforcing steel could not be precisely measured using the half-cell potential method, the characteristics of the deterioration and changes could be clearly observed when the results of polarization resistance and the current between the steels were also considered. These 10-year exposure tests have shown that the deterioration of reinforced concrete is influenced by characteristics of the concrete as well as the marine environment. (author abst.) |
