Abstract	This project assessed the five-year field performance of nine commercially-available, corrosion-inhibiting systems on reinforced concrete bridge barrier walls, and their laboratory performance using accelerated testing. The corrosion-inhibiting systems included concrete admixtures, reinforcing steel coatings, and/or concrete surface coatings/sealers. This paper reports on the laboratory testing that included assessment of the effect of the corrosion inhibitors on the oxidation and reduction reactions using the cyclic voltammetry method, and their effectiveness in delaying or reducing corrosion by measuring chloride thresholds and corrosion rates. Although laboratory testing could not exactly simulate field conditions, it was useful for identifying the effects of the corrosion inhibitors on the corrosion reactions, and providing supporting information for the field evaluation.
