Properties of Steel Fiber
Steel fibers are filaments of wire, which is deformed and cut into pieces, for reinforcement of concrete, mortar, and. Addition of steel fibers to concrete actually transforms a relatively brittle material into a ductile one. The key factors that decide the proportions of steel fibers in the mix design depend upon the physical properties required in the project. Therefore, it is important to look at the few steel fiber properties : Steel fibers are evenly distributed throughout a given cross section. However, reinforcing bars or wires are provided only according to their requirement. Steel fibers are relatively short. Small fibers tend to have greater control of cracks. This is an important consideration in designing the mix. Steel fibers are typically added to concrete in low volume dosage. The dosage is often as low as 1%. But, it has been proved to be effective in reducing plastic shrinkage cracking. The distribution of steel fiber reinforcement is provided b...
