Mechanical Properties of Glass Fiber Reinforced Concrete (GFRC)

Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, carbon, glass, aramid, asbestos, polypropylene, etc. The addition of these fibers into concrete mass can dramatically increase the compressive strength, tensile strength, flexural strength and impact strength of concrete. FRC has found many applications in civil engineering field. Based on the laboratory experiment on fiber reinforced concrete (FRC), cube, cylinders and beams specimens have been designed with glass fiber reinforced concrete (GFRC) containing glass fibers of 0% ,0.1% ,0.3%and 0.5% volume fraction . Comparing the results of GFRC with plain concrete, this paper validated the positive effect of glass fibers with percentage increase in compression, splitting and flexure improvement of specimens at 7 and 28 days.
