Abstract: An active steel repassivator for the rehabilitation of chloride contaminated reinforced concrete structures and a method for the application of same is disclosed. The active steel repassivator is comprised of a continuous phase, a distributed phase, and/or an aqueous solution of an amine. The continuous phase, also known as the carrier phase, is selected from organic strong volatile bases, salts of weak volatile acids and a non-ionic surfactant. The distributed phase includes an anion containing vanadium in the null4 or null5 state of oxidation. The aqueous solution of the amine acts as a co-inhibitor in the composition.
