Engineering practices have tried to change that behavior, by deploying rebars, which are steel rods embedded in concrete. Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It is therefore imperative that the behaviour under thermal stresses for the two materials be similar so that the differential deformations of concrete and the reinforcement are minimized. Steel Fibre Reinforced Concrete or SFRC is produced by mixing little amount of steel fibres in the elements of concrete. The concrete bases may be … Following are the different type of fibers generally used in the construction industries.
