In view of the large deviation of the effect of organic steel corrosion inhibitor in simulated pore solution and concrete, a dry-wet cycles test apparatus for accelerated evaluation of organic steel corrosion inhibitor was developed based on the concrete simulated pore solution and the controllable temperature and humidity. Four test systems were used to examine acceleration effects and test deviations of steel corrosion. The deviation of the test results of the organic steel corrosion inhibitors is significantly minimized via accurately controlling the test environment parameters and optimizing the acceleration systems. The results of the steel bars in the simulated pore solution and the concrete have a stronger correlation. Also, organic steel corrosion inhibitor, such as imidazoline, carboxylic acid amine and amino alcohol, effectively inhibits the rapid corrosion of steel bars under the condition of dry-wet cycles in chloride salt environment.
