Fiber Reinforced Concrete
Fiber reinforced concrete is a composite material consist of conventional concrete reinforced with fine fibers. The commonly used fibers are steel fibers, glass fibers, organic polymers fiber etc.
Plain concrete is weak in tension and has a low resistance to cracking. This weakness can be removed by the inclusion of fibers in the concrete mix.
The fibers help to transfer loads at the internal micro cracks. The commonly used fibers are steel fiber, glass fiber, organic polymers fiber, etc. Naturally occurring asbestos fibers and vegetable fibers are also used.
It is suitable for construction of hydraulic structures, airfield, lining works, highway pavements etc.
