An Experimental Investigation of Steel Fiber Reinforcement in High Performance Concrete

Abstract

One of the vital qualities of high performance concrete reinforced with steel fiber (SFRHPC) is its ability to resist cracking and crack propagation. HPC is the concrete that satisfies unique requirements of consistency and uniformity that can only be done routinely with the use of traditional materials and minimal grinding, placement and healing. The application of fiber to HPC improves its ability to arrest cracks, fiber composites have improved extensibility and tensile strength, both at first and ultimate cracking, particularly under flexural processing, and even after substantial cracking, the fibers hold the matrix together. The net result of all this is to send a pronounced post to the fiber composite-unheard of ductility breaks. The transition from a brittle material to a ductile type of material would substantially improve the energy absorption properties of fibre and its capacity to resist continuous use and impact loading.
