Concrete has a high compressive strength but is weak in tension and brittle. Cracks begin to form as soon as the concrete is poured. These three disadvantages prevent the use of standard concrete in pavements because they cause ductility, fracture, and failure. Concrete's shortcomings can be reduced by employing fibres as reinforcement in the concrete mix. Waste products such as polyethylene and tyres pollute the environment, resulting in a variety of health issues. Polyethylene and scrap tyres can be recycled and utilised efficiently as fibre reinforcement in concrete. Polyethylene is a synthetic hydrocarbon polymer that can increase ductility, strength, shrinkage, and other properties. This research investigates the effects of polyethylene fibre addition on the characteristics of concrete. Polyethylene and tyre fibres were chopped into 30mm x 6mm pieces and used at 1.5% by volume each. M30, M35, and M40 concrete grades were used. For the design of the concrete mix, IRC 44:2008 was used. The results of the Strength characteristics of Polyethylene fibre reinforced concrete have been provided in this study. Flexure and shear strength were determined in the laboratory using a four-point bending test and a double shear test. The 28-day compressive strength increased by 18%, while flexure and shear strength increased by 39% and 32%, respectively. The trials revealed a 22% decrease in deflection in the 4 point bending test and a 36% decrease in the double shear test. Theoretical study of deflection was performed using energy methods. Within the acceptable limits, practical values were validated against theoretical values. Finally, it is possible to conclude that polyethylene and tyre can be efficiently used in reinforced cement concrete.
