Keywords:Corrosion environment sensor, Concrete simulated solution, Chloride ion concentration, Corrosion rate

The corrosion detection performance of the corrosion environment sensor was examined in a concrete simulated solution. In the test, two kinds of test environments were prepared to supply air with reduced carbon dioxide concentration and oxygen to calcium hydroxide solution. The results of the sensor rupture time and the corrosion rate of steel were compared in each test cell.
