Fiber reinforced concrete- Application, Advantage, and ...

Fiber-reinforced concrete is concrete mixed with suitable fiber which increases its toughness. Fiber acts as micro reinforcement which increases the structural reliability of concrete. Concrete is weak in tension. The tensile strength of concrete is only one-tenth of the compressive strength of concrete.
