Analyzing the Application of Untreated and Treated Rubber Aggregate on The Mechanical Properties of Concrete

The disposal of waste tyres poses a serious environmental challenge due to their non-biodegradable nature and increasing generation worldwide. Incorporating waste tyre aggregate in concrete has emerged as a sustainable alternative that addresses both solid waste management and conservation of natural aggregates. This study investigates the feasibility and performance of concrete in which a portion of conventional fine aggregate is replaced with processed waste tyre aggregate. Emphasis is placed on evaluating the mechanical properties of tyre aggregate concrete under varying replacement levels. Experimental results indicate that the inclusion of waste tyre aggregate leads to a reduction compressive strength compared to conventional concrete. Higher replacement ratios adversely affect strength parameters, optimized proportions show potential for non-structural and semi-structural applications such as pavements, barriers, and vibration-damping elements. The present study deals with the comparative study of untreated and acetic acid treated rubber aggregate on the mechanical properties of concrete. The study highlights that with proper mix design and proportioning, waste tyre aggregate can be effectively utilized in concrete, contributing to sustainable construction practices by reducing environmental pollution and promoting resource efficiency.
