Fiber or BRC for concrete reinforcement.. Advantages of Fiber Reinforced Concrete Fiber is cheaper in price . Fiber mesh reduces shrinkage and cracking of concrete. Similar to other reinforced concrete, it improves the tensile strength of concrete. Reduces the chance of spalling since the fiber inside melts and allows the water content in concrete to escape. It is easy to include fibers in the concrete mix design. Polymer fiber reinforcement offers better corrosion resistance compared to steel r
