Advantages and use of steel fiber

The advantages of steel fiber mainly include the following aspects:

Increase the tensile strength and toughness of concrete: Adding an appropriate amount of steel fiber can significantly improve the tensile strength of the concrete, reduce the emergence of cracks, and prevent the expansion of cracks, thereby improving the service life of concrete. In addition, steel fiber can also improve the toughness of concrete, so that it is not easy to rupture when it is impacted and deformed.

Enhanced the durability of concrete: Steel fiber can make the concrete surface tight higher, prevent the penetration of water and chemicals, and improve the durability of concrete. The life span of steel fiber concrete exposed to high -speed water flow can reach more than three times that of conventional concrete life.

Improve the impact performance of concrete: The mixed amount of steel fibers in the concrete can significantly improve its impact resistance, and the ability to resist impact or vibration load can be increased by several times to dozens of times.

Improving shrinkage performance and anti -fatigue performance ‌: The contraction value of steel fiber concrete is low, anti -bending and pressure -resistant fatigue performance has greatly improved compared to ordinary concrete, and can significantly extend the life of the concrete.

Good high temperature intensity and corrosion resistance: Steel fiber has a microcrystalline structure, high strength and toughness, and can still maintain good strength and corrosion resistance at high temperature environments.

The use of steel fibers is very wide, mainly including the following aspects:

Industrial underground plates, warehouses, factories, airplanes, highways, bridges, parking lots, airplane tracks, parking apron and sliding lanes: These places require high -intensity concrete structures to bear heavy load and frequent use. Steel fiber concrete can be able Meet these requirements

Tunnels, dams and stability: In tunnels and dams, steel fiber concrete can provide better stability and durability, suitable for complex underground space and long -term water pressure environment.

Structural surface exposed to high -speed water flow environment: such as dams, ports, etc., steel fiber concrete can significantly improve its durability and service life.
