The polymer mortar has high strength, fast construction speed and short construction period. The shrinkage of polymer mortar is small, which reduces the generation of cracks, effectively prevents carbon dioxide, and can prevent carbonization of concrete. The polymer mortar has good freeze-thaw and durability. Its mechanical properties are similar to those of concrete, and it has permeability, which improves the long-term bonding performance. Good fire resistance, corrosion resistance and aging resistance. High-strength steel wire rope has high strength, and its standard strength is about 5 times that of ordinary steel, so the increase in the dead weight of the structure after reinforcement is small. In the process of structural reinforcement, it does not affect the use of the building, there is no requirement for the flatness of the surface of the reinforced component, and the joint handling is convenient, which can reinforce the concrete structure with defects or low strength. Flexural reinforcement can not only significantly increase the bearing capacity, but also significantly increase the stiffness, which is not comparable to carbon fiber reinforcement. The problem of durability and high temperature resistance after reinforcement is solved, and the reinforcement performance is reliable.
