The paper summarizes the results of many years of joint research carried out at the Chemistry Faculty of BSU and the Civil Engineering Faculty of BNTU on the development of a composition containing migratory corrosion inhibitors for reinforcement steel in concrete. The composition is intended for surface treatment during the repair of existing reinforced concrete structures. The main active ingredients of the water compositions are amino components—diethanolamine (DEA) and cyclohexylamine (CHA), as well as auxiliary components sodium benzoate and potassium dihydrogen phosphate. For better wetting of the concrete surface, the composition contains a surfactant. The accelerated electrochemical methods for studying the effectiveness of studying the corrosive and penetrating action of the compositions have been tested. Sodium chloride solutions were used as a corrosive medium. It is shown that the developed MCI composition in an aggressive corrosive environment of sodium chloride significantly slows down the corrosion processes of reinforcing steel in the structure of concrete, and its components are able to migrate along the pore structure of concrete.
