Fibre reinforced concrete is a composite material consisting of cement paste, mortar or concrete with closely spaced and uniformly dispersed fibres of polypropylene, nylon, asbestos, coir, glass and carbon (circular or flat).
Fibres introduced in concrete impart the following properties:
Increased static and dynamic tensile strength
Improved impact strength
Limited crack growth
Increased strain capacity
Because of the increased static and dynamic tensile strength, energy absorbing characteristic and better fatigue strength, fibre reinforced concrete has been used in:
Overlays of air fields, road pavements, industrial floorings and bridges decks etc.
Canal and refractory linings
Explosive resistant structures
Precast products such s pipes, beams, staircase steps, wall panels, proof panels and manhole covers etc.
