The main function of steel fiber

1. The main function of steel fiber is to hinder the expansion of micro-cracks inside concrete and block the occurrence and development of macro-cracks. Therefore, its tensile strength, shear resistance, bending resistance and torsion resistance are significantly improved.
2. The shrinkage value of steel fiber concrete decreases with the increase of fiber content.
3. The durability of steel fiber concrete has been improved to varying degrees under the action of various physical factors.
4. Steel fiber concrete has been proven by numerous experiments by researchers to have good corrosion resistance in air, sewage and seawater.
