Utilization of Waste Rubber Tyres in Concrete: An Experimental Study on Strength Characteristics with Partial Coarse Aggregate Replacement

Abstract

The disposal of waste rubber tyres has become a major environmental concern due to their non-biodegradable nature. This study explores the use of shredded waste tyre rubber as a partial replacement for coarse aggregate in concrete. Concrete mixes were prepared with 5%, 10%, 15% and 20% rubber replacement, along with a control mix. Compressive strength tests were conducted at 7 and 28 days. The results show that strength decreases with increasing rubber content, but lower replacement levels can still provide acceptable performance. The study demonstrates that rubberized concrete can be a sustainable solution for waste tyre utilization while reducing environmental impact and conserving natural resources.
