Fiber reinforced concrete: developments and applications to buildings

Abstract This report introduces the properties and applications of three newly developed fiber reinforced concretes. CFRC is a concrete made with carbon fibers distributed uniformly throughout cement mortar. CFRC has better tensile and flexural properties, toughness, and durability than conventional concrete. New GRC is made with cement which is less alkaline and less contractile, and alkali-resistant glass fiber with high zirconia content. New GRC has made it possible to produce larger interior and exterior panels. 3D-FRC is a concrete reinforced with three-dimensional fabric which is made by weaving fiber rovings in three directions. Continuous-fiber FRCs such as 3D-FRC feature more efficient reinforcement and produce stronger members than do short-fiber FRCs. These FRCs have been applied to secondary structural members such as curtain walls. FRCs are expected to become more common in the future.
