Steel fiber is a new type of composite material, which is widely used in civil engineering, automobile, shipbuilding, aerospace and other fields due to its high strength, high rigidity and high temperature resistance. This article will introduce the basic properties, applications and development trends of steel fibers in detail. Steel fiber manufacturers
First, the basic properties of steel fiber.
Steel fiber is a fibrous material with steel as the main component, and its diameter is generally 02-0.Between 9mm, the length is usually 20-50mm. Due to its high strength, high rigidity, high temperature resistance and other characteristics, it is widely used in various fields.
1.High strength and rigidity.
Steel fibers have high tensile strength and elastic modulus, which can effectively improve the strength and rigidity of composite materials. At the same time, the shear strength of steel fibers is also very high, which can effectively transmit and disperse stresses.
2.High temperature resistance.
Steel fibers have good high temperature resistance and can maintain their mechanical properties at higher temperatures. In addition, steel fibers also have good corrosion resistance and wear resistance.
Second, the application of steel fiber reinforced concrete.
In the field of civil engineering, steel fibers are widely used in concrete structures to improve the strength and durability of the structure. At the same time, steel fiber can also be used in roads, bridges, tunnels and other projects to improve the bearing capacity and crack resistance of the structure.
Steel fiber reinforced concrete is a composite material composed of cement, aggregates, steel fibers and other additives, and it has a wide range of applications in roads, bridges, tunnels and other projects. The strength and toughness of steel fiber reinforced concrete have been greatly improved, so it can effectively improve the bearing capacity and crack resistance of the structure.
In road engineering, steel fiber reinforced concrete can be used to pave the pavement to improve the wear resistance and rutting resistance of the pavement, thereby prolonging the service life of the pavement. In addition, steel fiber reinforced concrete can also be used to make road anti-skid markings to improve road safety.
In bridge engineering, steel fiber reinforced concrete can be used to make the load-bearing structure and bridge deck pavement of bridges to improve the bearing capacity and durability of bridges. In addition, steel fiber reinforced concrete can also be used to make anti-collision guardrails for bridges to improve the safety of bridges.
In tunnel engineering, steel fiber reinforced concrete can be used to make the lining and inverted arch of the tunnel to improve the bearing capacity and crack resistance of the tunnel. In addition, steel fiber reinforced concrete can also be used to make the waterproof layer of the tunnel to improve the waterproof performance of the tunnel.
In short, steel fiber reinforced concrete has a wide range of application prospects in roads, bridges, tunnels and other projects. With the continuous progress of science and technology and the continuous improvement of people's requirements for engineering quality, steel fiber reinforced concrete will be more widely used.
