We usually use carbon fiber reinforced polymer(CFRP) sheet for beam and slab reinforcement. Because of its advantages of convenient construction and simple operation.

However, carbon fiber fabric has some limitations. A large number of experiments have proved that the number of carbon fiber layers is not easy to exceed 4 layers. The number of layers is too large, and the reduction factor is increased, which can not play the role of structural strengthening. The CFRP plate reinforcement system can solve these problems.

The benefits of CFRP plate is for concrete strengthening

1.Corrosion resistance, long-term effect of 50 years 

2.Low cost,cost effective compared with other retrofitting method 

3.Easy installation, low installation cost 

4.Short construction period 

5.Light weight, no influence to original structure 

6.No maintenance required 

7.High tensile strength, design value:2600MPa, mean value:3100MPa

8.1 layers of CFRP laminate is equivalent to 4-8layers of CFRP fabric
