Use of Modern Composite Materials in Construction and Repair of Structures

Reinforced concrete elements of structures in the form of columns, beams, floors are widely used in the structures of buildings and structures of industrial and civil construction. One of the work cycles of reinforced concrete structures is the state of their repair and reconstruction, including the stages of strengthening the elements. There is a problem of reinforcing reinforced concrete columns. Although recently the need to strengthen structures has arisen even in the process of building structures. The article discusses the issue of reinforcing columns and other structural elements with a cylindrical surface with polymer composite materials in the form of carbon fiber lamellas and using carbon fabrics. The strength of the elements of reinforced concrete structures depends on many factors. And changing at least one of them leads to the loss of the bearing capacity of the object. In order to avoid cracks and other damage to columns, beams or slabs, it is necessary to additionally reinforce the structure with the help of polymer composite materials and, in particular, carbon fiber lamellas. To find out the reasons for the appearance of destruction and to choose the type of composite material, laboratory studies should be carried out. These tests affect the efficiency of composite reinforcement of reinforced concrete structures. The use of composite materials allows to increase the service life and strength of reinforced concrete structures used in construction.
