What are the reinforcement materials can effectively reinforce the structural beams?

1. Beam reinforced materials --- carbon fiber fabric

In recent years, using carbon fiber reinforced polymer(CFRP) reinforced concrete beams is a new advance techques. Because of its advantages of high strength and high efficiency, quick construction, good corrosion resistance, light weight without increasing the cross-section of components, etc. It has been widely used in projects, and in many cases, it has replaced various reinforcements and achieved significant economic and social benefits.

2. Beam reinforcement material --- bonding steel plate

Bonding steel plate is the use of high-performance structural adhesive bonded to the surface of concrete components, steel and concrete to form a unified whole, to achieve a good tensile strength,ability and rigidity of the load-bearing components.

3. Beam reinforcement materials --- section enlargement-anchoring adhesive

Increasing the cross-sectional method that is increase commercial concrete structures or structures to increase its carrying capacity and to meet the normal use of a method. With the construction process is simple, adaptable and so on. In the engineering, the concrete slab is replenished in the tension zone of the beam, which increases the effective height of the section of the beam, thereby increasing the rigidity and effectively improving the bending and shear resistance of the beam.
