Influence of Tire-Recycled Steel Fibers on Strength and Flexural Behavior of Reinforced Concrete

Table 1

Performance parameters of steel fibers.

Type	Tensile strength (MPa)	Bending resistance	Equivalent diameter (mm)	Length (mm)	Manufacturing process	Shape	Remark
Tire-recycled steel fibers	1260	Up to standard	1.0	35.34	Cutoff	Indentation on the surface	Uniform, neat cuts, and a small amount of rubber adhesion on the surfaces
Industrial steel fibers	990	Up to standard	1.0	36.02	Milling	Hook at the end	Uniform, neat incision, and shiny surface
