Abstract: In the present research the corrosion behavior of AISI 316 Stainless Steel was analyzed, as reinforcement in Green Concrete made with Low Volume of Sugar Cane Bagasse Ash (SCBA) and Silica Fume (SF), compared to AISI 1018 steel. Four concrete mixtures were made, all with a ratio w / c = 0.65, the percentages of substitution were 0%, 10%, 20% and 30%. The specimens were exposed in seawater as an aggressive medium, corrosion was evaluated by monitoring the corrosion potential Ecorr (ASTM C-876-15) and corrosion rate icorr (ASTM G59). The results of Ecorr and icorr after 150 days of exposure show a better performance of AISI 316 steel, with a 10% of probability corrosion and a negligible level of corrosion respectively, the Green Concrete with 30% partial replacement of the CPC by the combination of SCBA-SF presented the best protection against corrosion.
