    Abstract. One of the main reasons for the destruction of reinforced concrete is the corrosion of reinforcement. In this regard, the purpose of the research is to study the methods of active protection of reinforcing steel with special coatings in building structures. The nature of the occurrence of corrosion and the causes of corrosion processes in reinforced concrete structures are described. It is shown that not in all cases of using low permeability concrete, the reinforcement steel can be protected from corrosion. In a number of structures operated under the influence of aggressive chlorine-containing media, reinforcement protection with special coatings is required. It is clarified that in Russia today, methods of active protection of reinforcement of building structures from corrosion agents are practically not used (direct coating of reinforcement with epoxy or polymer-epoxy compounds). The developments of anticorrosive coatings in Russia and abroad over the past years are analyzed. Methods of active protection of reinforcing steel in building structures are presented: hot-dip galvanizing, coating with epoxy and polymer-epoxy compounds, the use of stainless steel fittings. The results of the study of physical and mechanical parameters of reinforced concrete elements exposed to aggressive media are presented. The conclusion is made about the relevance of the application and implementation of these reinforcement protection technologies in Russian building practice.
    Keywords: reinforcement corrosion, anticorrosive protection, aggressive environment, reinforced concrete structures, reinforcing steel, hot-dip galvanizing, epoxy coatings
