Carbon fiber reinforced reinforced concrete structure

Strengthening the structure of buildings and structures can be done in different ways. But in modern reality, one of the most effective methods is to use carbon and composite materials.

It is recommended to use semi-finished products made of composite materials and carbon materials to strengthen building structures, buildings and structures, because they:

• In terms of physical and mechanical properties (modulus of elasticity and ultimate tensile, bending and shear strength), carbon fiber materials are several times stronger than structural steel;

• The durable carbon fiber fabric used to reinforce the load-bearing structure is not easy to corrode, has high resistance to aggressive environments, and has almost unlimited service life;

• Lightweight carbon materials with the same strength are 10 times lighter than steel, so it is very convenient to use them to reinforce the structures of dilapidated buildings and historical monuments. These structures do not allow to increase the load of foundations, walls and floors.

  
  

Composite materials and carbon materials used to reinforce building structures can accomplish their tasks without changing the structural plan. Their use technology does not require large-scale work, and can be repaired without interrupting the normal operation of the facility. A small team completed the use of composite materials and carbon-based materials to reinforce the structure of buildings and structures in a short time.

The technical essence of using carbon fiber for structural strengthening

Carbon fiber is a linear elastic polymer composite made of carbon filaments 5 to 15 microns thick. Through alignment, the fine fibers are combined into microscopic crystals, thereby significantly improving the tensile strength of the material. Therefore, carbon fiber is several times that of metal in terms of technical properties (especially hardness), which allows it to be used in the defense industry, aerospace and construction industries.

One of the main advantages of the carbon fiber reinforcement method is that it is easy to implement. This technology involves the use of special adhesives to stick the carbon ribbon on the surface of the reinforcing element. After reinforcement, the carbon fiber tape can be directly connected to the tensile and compression elements, the span of the curved structure, the cantilever system, the short strut, and the flexible column. After external reinforcement, the polymer cement composition is applied to the surface, surface treatment and special acrylic paint are applied.

Carbon fiber reinforcement technology can be applied to various types of structures, including:

• RC;

• stone;

• metal;

• wooden.

Composite reinforcement methods are very suitable for building trusses, ceiling and wall openings, walls, floors, columns and other load-bearing components of buildings and structures.
