Concrete is incredibly strong in compression, but its tensile strength rates at one-tenth of that value. Adding macrofibres to the concrete mix design improves flexural strength. When done correctly, the tensile strength could increase by quite a large margin, nearly matching that of the compressive strength in some cases.
Advantages of Fiber Reinforced Concrete
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 reinforced concrete.
