The addition of fibres into concrete has been found to improve several of its properties like tensile strength, cracking resistance, impact, wear and tear, ductility, fatigue resistance etc. Many types of fibres like steel fibres, carbon fibres, GI fibres, glass fibres, asbestos fibres etc., can be used in fibre reinforced concrete. Waste plastics can also be used as fibres. The disposal of waste plastic is resulting in environmental pollution. Plastic is a non-biodegradable material, and it neither decays nor degenerates in water or in soil. On the other hand it pollutes the water and soil. Plastic if burnt releases many toxic gases, which are very dangerous to health. Such plastics can be used in concrete in the form of fibres to impart some additional desirable qualities to the concrete. This paper presents the results of waste plastic fibre reinforced concrete (WPFRC) produced from recycled aggregates subjected to acid and alkali attack. The different percentages waste plastic fibre used in the experimentation are 0%, 0.5%, 1%, 1.5%, 2%, 2.5% and 3% with an aspect ratio of 50. The results are compared with the waste plastic fibre reinforced concrete (WPFRC) produced from granite aggregates.
