Fiber reinforced concrete is a type of concrete that includes fibrous substances that increase its structural strength and cohesion. Fiber reinforced concrete has small distinct fibers that are homogeneously dispersed and oriented haphazardly. Fibers used are steel fibers, synthetic fibers, glass fibers, natural fibers, asbestos fibers and carbon fibers.
The concrete is placed on the surface to be covered, and is compacted in place using large heavy rollers typically used in earthwork. In this type of concrete, the mix achieves a high density and cures over time into a strong monolithic block. Roller compacted concrete is typically used for concrete pavement.
