Steel fiber reinforced concrete (SFRC) is a new type of multi-phase multi-component cement-based composite material, which is formed by randomly adding appropriate amount of short fiber into ordinary concrete. The properties of steel fiber produced by different manufacturing methods of steel fiber manufacturers are also different. Although steel fiber came out soon, it has been used more more widely. Low carbon steel fiber can be used for steel fiber reinforced concrete at room temperature, while stainless steel fiber must be used for fire-resistant steel fiber reinforced concrete. Adding proper amount of steel fiber into mortar concrete can improve its tensile strength, bending strength, toughness impact strength. It overcomes many shortcomings of concrete improves the physical mechanical properties of concrete. It has been applied in construction, highway bridge, water conservancy engineering, ocean engineering other fields. There are still many problems to be solved in the research application of steel fiber reinforced concrete. Among them, how to minimize the use cost, establish improve the production construction procedures, establish a reasonable structure theory system is the key research direction. Bluing steel strip
