The main structures of modern buildings are using a RC constructions. Timely work on strengthening and restoration of building structures is very important in practice. There are many accumulations with many different ways and constructive methods of strengthening RC constructions in different conditions of application. This article describes the modern methods and innovative materials for the strengthening and repairing of RC structures. The current state and trends of development in this direction in the field of re-equipment and reconstruction of RC elements of buildings and structures, which raised the issue of operational suitability are analyzed. Scientific works of scientists of many countries of the world in the field of experimental researches of strengthening of RC constructions are processed.
