Carbon fiber, carbon laminate: suitable solutions for reinforcing concrete structures

Carbon plates are 5 to 15 cm wide and 1.2 mm\1.4 mm thick strips made of various carbon fibers.

The process of reinforcement with carbon fiber or carbon fiber cloth involves installation by directly bonding the carbon fiber to a healthy precast concrete frame. This type of reinforcement is suitable for any place where tensile steel is lacking. Some examples:

• Reinforcement of curved slabs and beams

• Containment concrete pole

• Punching reinforcement

• Balcony bending reinforcement

• Deformation control (prestressed carbon reinforcement)

• Hopper or open door

• Strengthen the shear on the beam

Even though it plays the same role as traditional reinforced concrete reinforcement, this composite material has more advantages in terms of weight because it is lighter than concrete, faster to install than concrete, and thinner. And adapt to all types of structures.

This work is carried out on site and is different from the traditional repair process. The traditional repair process is usually very cumbersome and cumbersome (gluing the metal plate under the floor surface for support), so no preparation is required. Due to their lightness, their use in seismic zones will not change the distribution of forces within the structure due to earthquakes. Therefore, when used in seismic zones, there is no need to fully inspect the structure, but only to reinforce the area.

Application fields of carbon fiber laminate

This process makes it possible to deal with many issues related to new construction and restoration:

• Change the destination of the structure: increase the load

• Recover steel bars lost due to corrosion or other degradation

• Treatment of creep or fatigue problems: prestressed carbon reinforcement

• Design or production defects, especially reinforcement errors

• Increased weight-bearing capacity

• Reduce deformation or cracking: prestressed carbon reinforcement
