Which is better, steel fiber reinforced concrete floor or reinforced concrete floor?

Steel fiber reinforced concrete (SFRC) is a new type of multiphase composite material formed by adding randomly distributed short steel fibers into ordinary concrete. These randomly distributed steel fibers can effectively hinder the propagation of micro-cracks and the formation of macro-cracks in concrete, and significantly improve the tensile, bending, impact and fatigue properties of concrete, with good ductility. The fiber volume ratio of ordinary steel fiber concrete is between 1%-2%. Compared with ordinary concrete, the tensile strength, bending strength, shear strength and compressive strength are increased by 40%-80%, 60%- 120% and 50%- 100% respectively, and the compressive strength is increased slightly, generally by 0-25%.

The reinforced concrete ground in the equipment area, driveway area and warehouse area shall be constructed according to the second scheme. In the area with less load (such as staff rest area), backfill compaction is adopted, and C30 concrete with 12 thickness is laid on it, and double-layer bidirectional 10 diameter steel bars are used. The ground is one of the ways to increase the wear resistance of the surface layer. It is only necessary to pour a structural layer on the concrete or reinforced concrete floor, and it does not need to be very thick. Reinforced concrete is a kind of structural layer. Reinforced concrete structural layers are generally not made on the ground.
