Basalt fiber composite mesh has the following characteristics: high tensile strength, which can effectively transfer bonding stress;

The node strength is high and it is integrated with the concrete; the thermal expansion coefficient is close to that of the concrete, and the concrete will not crack due to temperature changes;

Corrosion-resistant, even if there are cracks in the early stage, the cracks will not expand; no magnetic wave transmission, does not affect the detection of the protective layer; high elongation and good deformation capacity.

Basalt fiber composite grid has the advantages of light weight, high strength, corrosion resistance, consistent thermal expansion coefficient with concrete, high node strength, and excellent bonding performance. It can be configured in the protective layer of the concrete structure, effectively alleviating and controlling the crack development and derivation of concrete under long-term external loads, and significantly improving the long-term durability and seismic resistance of the structure. In addition, the cracks in large-volume concrete are caused by the temperature difference between the inside and the outside. The tensile stress of the outer concrete is large, and the cracks first appear on the outside. The thickness of the protective layer of the basalt rigid grid can be much smaller than the thickness of the protective layer required by the steel mesh, so the anti-cracking effect is better.
