Mechanisms of localized corrosion of carbon steel associated with magnetite/mackinawite layers in a cement grout

Carbon steel electrodes covered with a specific low‐pH cement grout (pH ~10.7 at 20°C), designed for nuclear waste management applications, were immersed for 30 days in a 0.01‐M NaCl + 0.01‐M NaHCO3 solution (pH 7 measured at 20°C), in aerated conditions, at 80°C. The corrosion processes were studie...
