Коррозия стальной арматуры является одним из главных факторов разрушения железобетонных конструкций, подвергающихся воздействию агрессивных сред. Применение стальной арматуры с защитными покрытиями, наносимыми на ее поверхность в заводских условиях, является одним из важных направлений в создании долговечных железобетонных конструкций.</p></sec><sec><title>Цель</title><p>Цель. Показать возможные перспективы применения в России различных защитных покрытий арматуры для увеличения долговечности железобетонных конструкций в условиях воздействия агрессивных сред. Разработать предложения о необходимости выполнения научно-исследовательских работ для создания нормативной базы и внедрения в практику строительства арматуры с защитным покрытием.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Определение перспектив применения защитных покрытий арматуры в железобетонных конструкциях выполнено с помощью анализа научно-технической литературы, статей, нормативно-технических документов и информации из открытых источников по изучаемой проблеме.</p></sec><sec><title>Результаты</title><p>Результаты. Приведен опыт применения стальной арматуры с защитными покрытиями в России и за рубежом. Выделены наиболее применяемые технологии нанесения защитных покрытий на арматуру в заводских условиях. На примере исследований показаны основные достоинства и недостатки арматуры с защитным покрытием как в части долговечности самого покрытия, так и в части совместной работы с бетоном. Состояние отечественной и зарубежной нормативных баз значительно отличается друг от друга. В отличие от России, за рубежом создана обширная нормативная база, позволяющая выполнять проектирование железобетонных конструкций с арматурой с защитными покрытиями. На примере зарубежного опыта выявлены наиболее экономически целесообразные виды защитных покрытий. При некотором удорожании стоимости арматуры с защитными покрытиями по сравнению с обычной арматурой экономическая эффективность в целом достигается за счет увеличения межремонтного срока службы железобетонной конструкции.</p></sec><sec><title>Выводы</title><p>Выводы. Современная практика проектирования и строительства показывает, что для целого ряда железобетонных конструкций, эксплуатирующихся в условиях воздействия агрессивных сред, является необходимым применение арматуры с защитными покрытиями. Существуют большие перспективы применения арматуры с защитными покрытиями в России, однако в этом направлении необходимо развивать нормативно-техническую базу. По итогам анализа вопроса даны предложения о необходимости выполнения научно-исследовательских работ и перечень необходимых нормативно-технических документов для внедрения в практику строительства  арматуры с защитным покрытием.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Corrosion of steel reinforcement is one of the main factors of destruction of reinforced concrete structures exposed to aggressive environment. The use of steel reinforcement with protective coatings applied to its surface in factory conditions is one of the important directions in the creation of durable reinforced concrete structures.</p></sec><sec><title>Aim</title><p>Aim. To show possible prospects for the use of various reinforcement protective coatings in Russia to increase the durability of reinforced concrete structures under the influence of aggressive environment. To develop proposals on the need to carry out research work to create a regulatory base and introduce into practice the construction of reinforcement with a protective coating.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The determination of the prospects for the use of protective coatings of reinforcement in reinforced concrete structures was carried out by analyzing scientific and technical literature, articles, regulatory and technical documents and information from open sources on the problem under study.</p></sec><sec><title>Results</title><p>Results. The experience of using steel reinforcement with protective coatings in Russia and abroad is given. The most widely used technologies for applying protective coatings to reinforcement in factory conditions are highlighted. The main advantages and disadvantages of reinforcement with a protective coating are shown on the example of studies, both in terms of the durability of the coating itself and in terms of working together with concrete. The state of the domestic and foreign regulatory base differs significantly from each other. In contrast to Russia, an extensive regulatory base has been created abroad that allows the design of reinforced concrete structures with reinforcement with protective coatings. Using the example of foreign experience, the most economically feasible types of protective coatings have been identified. With a certain increase in the cost of reinforcement with protective coatings compared to black reinforcement, economic efficiency is generally achieved by increasing the service life of the reinforced concrete structure.</p></sec><sec><title>Conclusions</title><p>Conclusions. Modern design and construction practice shows that for a number of reinforced concrete structures operating under the influence of aggressive environment, it is necessary to use reinforcement with protective coatings. There are great prospects for the use of reinforcement with protective coatings in Russia, but it is necessary to develop а regulatory and technical base in this direction. Based on the results of the analysis of the issue, proposals are given on the need to carry out research and a list of necessary regulatory and technical documents for the introduction of reinforcement with a protective coating into the practice of construction.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>арматура</kwd><kwd>бетон</kwd><kwd>железобетонные конструкции</kwd><kwd>защитное покрытие</kwd><kwd>условия окружающей среды</kwd><kwd>арматура с цинковым покрытием</kwd><kwd>арматура с эпоксидным покрытием</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reinforcement</kwd><kwd>concrete</kwd><kwd>reinforced concrete structures</kwd><kwd>protective coating</kwd><kwd>environmental conditions</kwd><kwd>galvanized rebar</kwd><kwd>epoxy coated rebar</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">СП 63.13330.2018.
