Moisture conditions of concrete are a critical factor in the corrosion of reinforcement. In this study, various electrochemical measurements were conducted using reinforcement in concretes containing chloride ions with the moisture content adjusted to various values, thereby investigating the effect of the moisture conditions of concrete on reinforcement corrosion. In the range of this study, the following were found; In the range of this study, the relative moisture content of concrete below which incidence and growth of reinforcement corrosion is substantially suppressed is between 55 and 65%. When the relative moisture content of concrete is between 55 and 65% or less, substantial suppression of reinforcement corrosion is expected, even with a chloride ion concentration of 5.0 kg/m^3.
