DEVELOPMENT OF A CORROSION INHIBITOR FOR REINFORCED CONCRETE

Because of its highly alkaline concrete environment, reinforcing-steel surface is protected from corrosion by a thin oxide film. This film is maintained only in the absence of substances that form soluble complexes with iron. One of these substances is the chloride ion found in common deicing salt. Domtar Inc. established a research program to address the problem of rehabilitation of corroding reinforced-concrete structures. The experimental procedures and measuring techniques used to identify suitable corrosion inhibitors and typical results obtained with a selected inhibtor are presented. The inhibitor proved effective in reducing corrosion of steel embedded in concrete, and therefore it can be applied either as a curative or preventive means to protect reinforced-concrete structures.
