BACKGROUND
Fiber-reinforced concrete (FRC) is produced by mixing hydraulic cement, aggregates water, and reinforcing fibers. Synthetic fibers such as steel and polypropylene, or natural fibers such as hemp, sisal and others may be incorporated. The fibers orientation random, discrete, and discontinuous. Fiber-reinforced concrete is expected the strength, ductility, and durability requirements of a high performance concrete material FRC has been used in many applications such as slabs on grade, airports and pavements tunneling, rock stability, and shotcrete works (ACI544.1R-1996)
