Abstract

The increasing amount of waste material from industry is a concerning reality that has began the sustainability issues of the environment and ecology of earth surface. The production of fibre in the industry accounts for the global warming by releasing the carbon dioxide and other harmful gases in the atmosphere during its manufacturing. Concrete is a substance, which has high strength in compression and less strength in tension, so far increasing the tensile strength of the concrete, reinforcements are added. To increase the tensile strength and to prevent the growth of micro cracks of concrete to the macroscopic level, fibres can be added. The presence of micro cracks at the mortar- aggregate interface is responsible for the inherent weakness of plain concrete. The weakness can be removed by inclusion of fibres in the mix. Such a concrete is called fibre reinforced concrete (FRC). In this study polypropylene fibre was used as an additional material of cement concrete. Polypropylene fibre (PPF) is a synthetic hydrocarbon polymer which was added to enhance the strength of the concrete i.e. compressive and split tensile strength. The present proposal involves a comprehensive laboratory study for the newer application of this waste material in the preparation of fibre reinforced concrete. The primary objective of investigation is to study the strength behaviour i.e. compressive strength, and impact resistance of concrete with different lengths and densities of polypropylene Fibre.
