This paper describes a feasibility study on the injection of synergistic corrosion inhibitors for protection of concrete bridge components against corrosion. During this study corrosion inhibitors were developed that can be electrically injected into concrete matrices by an in situ technique. The results showed that such inhibitor injection can provide adequate corrosion protection to rebars embedded in chloride contaminated concrete. It was demonstrated that inhibitors injected can provide 78-85% corrosion protection for the rebars. Important advantages of this technology as against cathodic protection are its novelty and nondestructive nature and the lack of necessity for a permanent installation.
