Experimental Investigation on Usage of Waste Bottle Caps as Fiber in Concrete

Concrete with fiber reinforcement is a composite material composed of fibrous material that provides structural strength and integrity. Since, concrete is significantly brittle in nature and exhibits the poor tensile strength, the cracks are obtained at a faster rate and thus effects the reinforcement and starts to corrosion of steel. So, to overcome this issues the fibers are induced in concrete to prevent cracking and improve the strength. The addition of the bottle caps as fibers increases the strength parameters of the concrete. The compressive load carrying capacity induced with the bottle caps as fibers has provided greater strength but as the increase in the bottle caps as fibers the strength gradually decreases. The split tensile load carrying of concrete increases with induction of bottle caps as fibers in which the experiment up to 15% the bottle caps are added and the strength is increased. The flexural strength gets higher due to induction of the addition of the bottle caps up to 10% but after increasing the bottle caps as fibers to 15% the strength gradually decreased. The results from the experiment conclude that the compressive, split tensile, flexural strength of the concrete induced with the bottle caps as fibers to 10% is greater than the nominal mix.
