Steel fiber is widely used in road pavement, airport runway, industrial and warehouse floors, various culverts, tunnels, water conservancy engineering, ports, docks, seismic construction and other projects.In concrete is mainly limited to the expansion of concrete crack, so that its tensile resistance, bending resistance, shear strength is significantly improved compared with ordinary plain concrete, its impact resistance, fatigue resistance, cracking toughness and durability have been greatly improved, make the original brittle material concrete into a composite material with certain plastic performance, thus improving the structure of concrete, improve its service life, and can save engineering cost, has important economic and social benefits.
