Treatment measures for concrete cracks
Concrete crack is a common phenomenon in concrete structure. Its appearance will not only reduce the anti seepage ability of the building, affect the use function of the building, but also cause corrosion of steel bar, carbonization of concrete, reduce the durability of the material and influence the bearing capacity of the building, so it is necessary to enter the concrete crack.

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.
