How many kilograms of steel fibers are added to each cubic meter of concrete?

Steel fiber content varies depending on the project direction. The specific requirements are as follows:
1. Determined by the steel fiber material and the parts used in the project, the dosage of steel plate shearing type is generally 50 to 70 kilograms per cubic meter, and the dosage of steel wire cutting type is generally 20 to 30 kilograms per cubic meter. The steel plate shearing type is used for roads and bridges. The steel wire cutting type is used for the ping, which can be selected according to different projects.
2. Steel fiber concrete is a new multi-phase composite material formed by mixing random distributed short steel fibers into ordinary concrete. The randomly distributed steel fibers can effectively hinder the expansion of micro cracks and macro cracks inside the concrete. The formation of concrete significantly improves the tensile, bending, impact and fatigue resistance properties of concrete, and has better ductility.
