Steel Fiber Reinforced Concrete FAQ
When subjected to tensile stress, unreinforced concrete will crack and fail. Since the mid 1800’s steel reinforcing has been used to overcome this problem. As a composite system, the reinforcing steel is designed to carry the tensile loads. Steel fibers have been used for a similar purpose since the 1970’s. When fiber reinforcing is added to the concrete mix, it transforms the brittle concrete to a ductile composite system able to develop tensile load carrying capacity. Following are frequently asked questions by those new to steel fiber reinforced concrete.
