The use of the E-Log I curve as a means to determine the current necessary for cathodic protection of steel in concrete has been investigated. Cathodic polarization curves for steel in concrete were produced under various conditions, including time increment, moisture content, temperature and concrete cover. To investigate the applicability of E-log I tests on atmospherically exposed concrete, the cathodic polarization behavior of steel in concrete is compared to the polarization of steel in simulated concrete pore solution and an aluminum sulfate acid solution.
