Carbon Fibre Wrap For Concrete Columns Strengthening

CFRP Strengthening Systems are composed of carbon fiber fabric that are wrapped around a structure and coated with adhesive. Once dry, the systems strengthen concrete, masonry,and wood structures and can be up to 9 times stronger than steel, yet thinner and flexible.

Carbon fiber reinforcement in wharf retrofit project

In the design of CFRP reinforcement scheme for Wharf theme structure, the adaptability of seawater environment should be taken into account. At the same time, the durability of coatings, resins, repairing glues, primers, reinforcement materials and interface agents used in the reinforcement process should be considered.

Concrete slab wall enlargement section reinforcement

​The renovation project of kindergarten teaching building, with three-storey brick-concrete structure, has a building area of about 2800 m2. Because the original design was designed according to the old code, it is now checked in accordance with the current code and strengthened to those places that do not meet the current code. After strengthening, it is still used as a kindergarten teaching building, and the use function has not changed.

Bridge Structural Reinforcement

Because of the high strength and high elasticity of carbon fiber materials, the use of adhesives to paste them on the surface of the bridge, so that they can bear the load together with the bridge structure, can greatly improve the tensile, compressive and shear capacity of the bridge.

Carbon Fiber Reinforced Cracked Beam and Slab

The project has been effectively controlled in all aspects of CFRP reinforcement to ensure the quality of reinforcement. After carbon fiber reinforcement, the design intention has been achieved through joint acceptance by all parties, and it has received unanimous praise from Party A and supervision.

Comparison of Main Reinforcement Methods of Bridges

Using reinforcement method to strengthen and maintain the original bridge not only saves a lot of construction funds, but also solves the contradiction between the bearing capacity of the bridge and traffic demand in a short time. At present, the main methods used to reinforce bridges include enlarging section and reinforcing steel bar, bonding steel plate, external prestressing and carbon fiber sheet.
