 The study found that the coating on the steel rebar in coral concrete provided effective protection against corrosion. The corrosion rate remained low throughout the testing period, and the resistance factor, RP, was consistently higher than 250 k omega dot cm2. Additionally, the chloride ion diffusion coefficient, D, followed a power law relationship with the wet slash dry cycle time, and a time varying model for chloride ion concentration on the surface of coral concrete was developed. The surface chloride ion concentration increased from 0V to 0.14V over the first seven years, then decreased significantly afterwards. Finally, the cathodic zone of coral concrete members was the most active, increasing from 0V to 0.14V between 0 and 20 years, with a large increase in potential difference before the seventh year, and a significant decrease in the increase after the seventh year.
