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.

Post-installed Rebar Connections with Anchoring Adhesive
Post installed anchor with chemical anchoring adhesive is a simple and effective connection and anchorage technique for concrete structures, which can be implanted in ordinary steel and bolt anchorage. It is now widely used in strengthening and rebuilding of buildings.

Factors affecting chemical anchoring reinforcement
The bond between reinforcing bar and base material mainly depends on the adhesive force of chemical anchoring adhesive. Therefore, when selecting the hole diameter, the diameter of the rebar should be slightly larger than the diameter of the reinforcing bar, so as to ensure that the planting bar glue has a certain thickness to provide enough cohesive force.
