Concrete structure unsuitable for carbon fiber strengthening

Carbon fiber reinforced polymer(CFRP) wrap can be successfully used for concrete structure, seismic shear and flexural strengthening. But it should be pointed out that because many inherent characteristics of CFRP reinforcement structure, many concrete structures are not suitable for strengthening with carbon fiber, so it is necessary to analyze their applicability.

Carbon fiber reinforced polymer(CFRP) plate strengthening

1 layers of carbon fiber reinforced polymer(CFRP) laminate is equivalent to 4-8 layers of carbon fiber reinforced polymer(CFRP) fabric.Low cost,cost effective compared with other retrofitting method.Light weight, no influence to original structure

Pre-stressed CFRP laminate improve the flexural rigidity

1.The prestressed CFRP plate makes the concrete(because of the crack is out of work) in the lower part become the effective section

Prestressed CFRP laminate

The high strength properties of CFRP (carbon fiber reinforced polymer) can be brought into play in advance, and there will be greater strain before the two force, which can effectively reduce or even eliminate the phenomenon of CFRP sheet strain lag, and achieve better reinforcement effect.

Reinforcement of bridge with epoxy bonded steel plate

The bonding steel plate reinforcement method is to apply epoxy resin series adhesive on the steel plate, and then paste it into the weak part of the reinforced concrete structure's tensile area, the steel plate and the structure form the whole, and the additional reinforcing bar is added.

Poor bond between CFRP and concrete,why?

Externally bonded carbon fiber reinforced polymer(CFRP),it is a new advanced technical method for structural strengthening.But your CFRP can't bond with concrete,why? You can see the article, you can solve your problem。

Prestressed CFRP Laminate Strengthening

The prestressed CFRP laminate has been widely used in the structural strengthening in recent years with its unique advantages. Take full advantage of high strength of carbon fiber; make new structures and old ones work together, change the passive reinforcement to active reinforcement

Why can't choose basalt fiber for structural strengthening?

Most structure is reinforced with carbon fiber reinfroced polymer fabric(high strength ,high modulus). Why don't we choose basalt fiber for structural strengthening?
