Steel fiber concrete also has superior economy, and the intensity and weight ratio increased, making it widely used in civil engineering.
Steel fiber concrete is a new multi -phase composite material formed by short steel fibers mixed with distributed distribution in ordinary concrete
These steel fibers can effectively hinder the expansion of micro -cracks inside the concrete and the formation of macro cracks, significantly improve the concrete anti -tensile, bending, impact
impact and anti -fatigue performance, and have good delay. Ound
The physical mechanical properties of steel fiber concrete have significantly improved compared to ordinary concrete. Its tensile strength can be increased by 25%-50%, the bending strength is
increased by 40%-80%, the shear strength is increased by 50%-100%, and the pressure resistance intensity increases less, generally between 0-25%, but The pressure resistance is greatly
improved.
In addition, steel fiber concrete also has superior economy, and the intensity and weight ratio increased, making it widely used in civil engineering.
Steel fiber concrete is widely used in construction, bridges, tunnels, airport runways, port pier and other projects, because it can significantly improve the carrying capacity and earthquake
resistance of concrete. This material first appeared in developed countries in the early 20th century, and then started research and application in China and other countries, and gradually
promoted to all fields of civil engineering.

The difference between shear steel fiber and milling steel fiber
The tensile strength, bending strength, and impact toughness of the milling steel fiber 的 are relatively low, but its tensile and pressure resistance are particularly prominent, and it also has good crack resistance. The surface of milling steel fiber is rough, and the adhesive strength of the concrete can significantly enhance the tensile and bending strength of the concrete

By adding an appropriate amount of steel fiber to the concrete, it can significantly improve the mechanical properties such as tensile, bending, impact resistance and crack resistance, and transform the original brittle materials into composite materials with tough and ductility. In addition, steel fiber can also extend the life of concrete and reduce the possibility of cracking and fracture.
