Which is better, bonded steel reinforcement or carbon fiber reinforcement?

Compared with the traditional reinforcement by enlarging the concrete section or sticking reinforced concrete, carbon fiber has the characteristics of saving space, simple construction, no need for on-site fixing facilities, easy guarantee of construction quality, basically no increase in structural size and self-weight, good corrosion resistance and durability. In addition, this construction method can greatly improve the service life of the building and reduce the reinforcement cost. Therefore, carbon fiber, as an epoch-making reinforcing material, has attracted much attention. The tensile strength of (1) is high, which is 7- 10 times that of steel with the same section. (2) Light weight, and the density is only 1/4 of that of ordinary steel. (3) Good durability and resistance to chemical corrosion and damage caused by harsh environment and climate change. (4) The construction is convenient and quick, which saves labor and time, and the construction quality is easy to guarantee. (5) It has a wide application range and can reinforce concrete members, steel structures and wood structures. It can greatly improve the bearing capacity, seismic performance and durability of components.
