Carbon Fiber Reinforcement In Concrete

1. Introduction of carbon fiber reinforcement in concrete

The carbon fiber cloth reinforcement technology uses adhesive to stick the carbon fiber cloth to the damaged part of the concrete, integrating it with the concrete substrate to ensure that both are under common stress. It fully utilizes the good tensile strength of carbon fiber cloth to achieve the purpose of strengthening the bearing capacity and functional use of damaged components, thereby improving the bearing capacity of concrete components, reducing deformation of concrete components, and controlling crack propagation.

We support carbon fiber building reinforcement cloth with a width of 10 centimeters to 100 centimeters, which can be customized according to customer requirements.

Carbon fiber not only possesses the inherent characteristics of carbon materials, but also possesses the softness and processability of textile fibers, making it a new generation of reinforcing fibers. The best carbon fiber cloth is mainly divided into building reinforcement cloth, mesh cloth, pre impregnated cloth, etc. The product has the characteristics of light weight, high strength, high modulus, high temperature resistance (up to 2000 ℃), corrosion resistance, and fatigue resistance. Our company has won the trust of many customers with professional and advanced production technology. We value reputation, ensure product quality, and have obtained the international certification of lS0 9001:2015. We offer small profits, fast delivery, and sincere service.

2. Application scope of carbon fiber reinforcement in concrete

Carbon cloth reinforcement is only applicable to the reinforcement of reinforced concrete components under bending, tension, axial compression, and large eccentric compression, such as the reinforcement of building beams, slabs, columns, walls, etc.

Not recommended for reinforcement of small eccentric compression components. This is because fiber-reinforced composite materials are only suitable for bearing tensile stress, and the longitudinal tensile steel bars of small eccentric compression members cannot reach the yield strength. Using adhesive fiber-reinforced composite materials will cause great material waste.

4. Typical Uses of carbon fiber reinforcement in concrete

Reinforcement and seismic strengthening of concrete structures, masonry structures, and timber structures

lt is especially suitable for structural reinforcement of complex forms such as curved surfaces and nodes;

Reinforcement and repair of various structural types and structural pats, such as beams, slabs, columns, roof trusses piers, bridges, cylinders, shells and other structures.

5. Features of carbon fiber reinforcement in concrete

1. Carbon fiber cloth has the characteristics of lightweight and high strength. After reinforcement, it basically does not change the external dimensions of the original structure and does not increase the weight of the original structure itself.

2. The construction process of carbon fiber cloth reinforcement is simple, the construction period is short, and it effectively saves time and costs.

3. Carbon fiber cloth has a higher elastic modulus, and after reinforcement, it has a better control effect on small deformations such as temperature cracks and rust expansion cracks.

4. Carbon fiber cloth has better flexibility compared to other materials and is suitable for strengthening various forms of structures.

5. Carbon fiber cloth has advantages such as chemical corrosion resistance, acid and alkali resistance, and other harsh environmental corrosion.

6. Notes

A. The on-site measured concrete strength grade of the reinforced concrete component shall not be lower than C15, and the positive tensile bonding strength of the concrete surface shall not be lower than 1 5MPa.

So, why is it necessary to specify the measured strength of concrete? The professional explanation is provided in General Rule 10.1.2 of the Code for Design of Concrete Structure Reinforcement (GB50367-2013).At the same time, we also need to treat the base surface, polish the edges and corners (with a radius of no less than 25mm), dry it, etc. Please refer to Article 10.2.1 of the "Code for Acceptance of Construction Quality of Building Structure Reinforcement Engineering" GB50550-2010 for details.

B.When reinforcing reinforced concrete structural components with external fiber composite materials, the fiber stress mode should be designed to only withstand tensile stress.

C.The Code for Design of Concrete Structure Reinforcement GB50367-2013 specifies that the long-term use temperature of carbon cloth reinforcement should not exceed 60 ℃. But it should be pointed out that this is determined based on the performance of ordinary adhesives under normal temperature conditions. When using high-temperature resistant adhesives, this limitation is not applicable, but it should be subject to the current national standard "Code for Design of Concrete" GB 50010, which limits the ability of concrete structures to withstand productive high temperatures.

D.When using fiber composite materials to reinforce reinforced concrete structures, measures should be taken to remove or partially remove the live load acting on the structure.
