Steel fiber concrete is a type of fiber-reinforced steel concrete. It is produced from fine grain concrete or heavy concrete (concrete-matrix), in which instead of a rebar, steel fibers are used, evenly distributed over all the volume of concrete. Interaction of concrete and steel fiber is achieved by means of adhesion on their surfaces and fiber anchoring by means of periodic profile and its crookedness in longitudinal and transversal direction. Currently, steel fiber concrete is a perspective construction material which is used in many industrial developed countries in the world. Appearance of new specially produced types of steel fiber – wire fiber of anchor, wavy and straight profile, as well as utilization of powerful chemical modifiers super- and hyper plastifiers made it possible to set steel fiber concrete on a new technological plane which extends its sphere of application and at the same time physical and mechanical characteristics of concrete increase considerably: tensile strength in bending, crack resistance, shock resistance, etc. With appearance and development of monolithic concrete, new material found its niche. Presently, fiber, as a reinforcing component, is utilized in the following types of construction: in monolithic construction when making floors for industrial buildings, storage rooms in logistic centers, flight strips at airports, car parks and motor roads, basins and swimming pools, bank vaults and safes, blastproof fortification objects, as well as in other spheres of construction with high strength properties of concrete structures; in assembly steel fiber concrete – reinforced tubes of big diameter, metro tubing, elements of wall panels and ceiling panels, railway sleepers, road slabs, small architectural shapes, etc.
