1.General Introduction of the Steel Fiber
The milled steel fiber is made of high strength steel wire through milling process, which makes the wire into wave shape to increase the touching area with concrete. By tightly binding with the mortar, the steel fiber can greatly enhance the performance of steel-fiber reinforced concrete, with strong cracking and shearing resistance, and tensile strength.
