About steel fiber concrete reinforcement
Steel fiber reinforced concrete (SFRC), as its name suggests, is concrete that has been reinforced with steel fibers. Steel fibers bridge the crack at very small crack openings, transfer stresses and develop post crack strength in the concrete. Unlike conventional reinforcement, which consists of steel bars or mesh, steel fibers are relatively short, discontinuous elements that are randomly distributed throughout the concrete member.
Further, traditional reinforcement is provided at distinct locations, whereas steel fibers form a homogeneous reinforcing network across the entire concrete cross-section, thus providing increased strength.
