Carbon fiber reinforcement materials are high-strength carbon fiber unidirectionally arranged fibers, which are impregnated with a small amount of resin and used as a repair and reinforcement material for concrete. Its tensile strength is more than 10 times that of ordinary secondary steel bars.

Carbon fiber reinforced materials can be widely used in the reinforcement of beams, columns, shear walls and slabs: can increase the ductility (seismic capacity) of the columns by 2 to 4 times;

Improve the bending capacity of beams and slabs by 30% to 100%;

Enhance the shear capacity of beams and columns by 30%-80%;

Improve the bearing capacity of columns and walls by 20% to 50%, especially suitable for various curved structures.

At the same time, carbon fiber reinforced materials have good durability, resistance to acid, alkali, salt and atmospheric environment corrosion, saving space, simple construction, no need for on-site fixed facilities, easy construction quality assurance, can greatly improve the service life of buildings and reduce reinforcement costs.

In short, the superiority of carbon fiber materials in concrete repair is obvious.
