How to thickening concrete beams by post installed anchor
Beam thickness strengthening method must ensure that the new and old concrete has higher bond strength. The main points are as follows: the base course of the original component joint surface should be solid, the surface is rough and clean, the shrinkage stress of the new cast concrete is small, and the bond performance is good.

Main application forms of FRP strengthening
CFRP wrap has high tensile strength and fatigue strength in the direction of CIS fiber, and the compression and shear strength are relatively low, so it is mainly adapted to the reinforcement of the tensile region of the concrete structural members, but the CFRP can be circular or U around the concrete members, so it can also be used for the compression of concrete members or shear reinforcement.

New structural strengthening method of Civil Engineer
According to the different additive properties. The addition of the structural strengthening includes three aspects: bearing capacity (strength) reinforcement, service function (rigidity) reinforcement and durability reinforcement.

Prestressed CFRP laminate VS Prestress wire
In recent years, the concept of prestress in the field of building structure has been mentioned by more and more people. In the field of structural reinforcement, the application of prestressed reinforcement technology is developing faster and faster. There are two main ways of prestressed reinforcement: prestressed FRP laminate and Prestress wire.
