СПОСОБИ ВІДНОВЛЕННЯ ОГОЛЕНОЇ ІРЖАВОЇ АРМАТУРИ В БЕТОННИХ КОНСТРУКЦІЯХ

The article presents a detailed scientific review of modern technologies and methods for restoring exposed rusty reinforcement in concrete structures that have undergone corrosion processes due to aggressive external environments or non-compliance with technologies during construction. The effectiveness of mechanical cleaning of the reinforcement surface, chemical treatment using acidic compositions, the use of corrosion inhibitors of organic and inorganic origin, the introduction of electrochemical (cathodic) protection using external current sources and the use of specialized repair solutions that provide a protective layer around the reinforcement is considered. A substantiated assessment of the advantages, disadvantages, and areas of appropriate application of each of the methods is provided, taking into account operating conditions, durability, economic feasibility, and technical complexity of implementation. Illustrative material in the form of diagrams and photos allows you to visualize the key technological stages of intervention and contributes to the formation of a holistic idea of ​​​​the choice of the optimal approach to the repair and strengthening of structures.
