Abstract
The electrochemical behavior of the corrosion resistance of AISI 304 embedded in concrete manufactured as indicated by the ACI 211.1 method was evaluated. The specimens were exposed for more than 150 days to highly aggressive marine-sulfated environment, solution with a concentration of 5% NaCl and 5% Na2SO4. The electrochemical technique of Resistance to Linear Polarization (Rp) was used for to determine the corrosion rate (Icorr) and monitoring of corrosion potential (Ecorr). The Ecorr and Icorr results indicate a high level of corrosion for AISI 1018 steel, on the contrary, the electrochemical behaviour of AISI 304 steel according to the values of Ecorr and Icorr, indicate a corrosion resistance of up to 10 times higher when exposed to an environment with a high concentration of chlorides and sulfates.
