Difficulties and solution in prestressed FRP laminate strengthen
The key difficulty of the prestressed CFRP reinforcement technology is to solve the relationship between the anchorage and the carbon plate, the anchorage and the concrete. The HM prestress prestressed FRP plate not only makes up the defects of the CFRP, but also have more key features can solve more problem.

The basis for judging the quality of the anchoring adhesive
The uniformity of bond strength of anchoring adhesive concrete specimens: each type of glue, C25 concrete specimen size 280x300x600mm, 3 groups.

Anchoring rebar adhesive and chemical anchor bolt
Because the basic functions and principles are very similar, it is always difficult to make clear the anchoring adhesive and anchor bolts.

What are the requirements of the prestressed CFRP laminate
The prestressed CFRP laminate is a kind of active reinforcement technology applied to bridge, long span beam and other flexural members. It does not increase the weight of the original component and can be strengthened without unloading, so it is favored.

It is important to select good anchoring adhesive for strengthen
In the field of reinforcement, post installed anchoring can significantly improve the seismic performance of buildings, so it has been widely used in recent years. The glue used for planting reinforcing rebar is also called anchor adhesive. Its quality affects greatly the effect of planting rebar.

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.

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.

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.
