Experimental Investigation on Jute Fibre Reinforced Concrete with Partial Replacement of Fine Aggregate by Plastic Waste

Abstract

Plastic waste is the major cause of environmental pollution and hence it should be recycled or reused to reduce it. Plastic wastes are used as fine aggregate in a severalquantities in the jute fibre reinforced concrete and check their aptness. This study investigates the effect of using plastic waste as an alternative for fine aggregate. The PET plastic bottle is injurious to land and health, hence the usage of plastic waste in the concrete will lead to protect the environment and human health. The partial replacement of fine aggregate and coarse aggregate are the major components in the concrete. In India tons of plastic wastes are produced per year hence by reusing in the concrete can decrease the wastages. The jute fibre is one of the natural fibre and it is used in plastic waste concrete to increase the split tensile strength and flexural strength of the concrete. The present study has been conducted on M20 grade concrete, by replacing fine aggregate by PET plastic waste for varying percentages such as 5, 10, 15 and 20%. The PET plastic concrete is optimized as 10% from the mechanical properties of concrete. The jute fibre is added for 0.25, 0.5, 0.75, 1% for various proportions by volume of optimized plastic waste concrete. The properties of fresh and hardened concrete were evaluated and compared. The experimental results of companion specimen show that the mechanical properties of plastic waste concrete increases with 0.25% of jute fibre in concrete. Utilization of M Sand and PET plastic aggregates in concrete leads to minimize the cost of construction and leads to sustainable environments. The natural fibres in concrete increase the strength of concrete.
