Enhancing High-Performance Concrete with Waste Rubber Tyre Aggregates: A Sustainable Approach

Every year, millions of old rubber tyres are thrown away, and because of the difficulty in disposing of non-biodegradable materials, this poses health and environmental risks. In recent years, the construction industry has been forced to use this material in combination with cement-based products due to its accessibility and substantial production volumes. This study investigates the feasibility of using rubber tyre flakes instead of some traditional particles in concrete. The properties of rubber concrete are examined with respect to different proportions of conventional aggregates and waste rubber tyres. Previous studies have shown that using waste rubber tyres as aggregate significantly reduces the mechanical properties of concrete, including tensile, flexural, and compressive strengths. However, using waste rubber tyres as an aggregate will reduce the weight of concrete, which can be helpful in structural construction. This study investigates the incorporation of waste rubber tyre aggregates to enhance the properties of high-performance concrete, presenting a sustainable approach toward construction materials. The primary objective is to assess the mechanical, durability, and environmental implications of utilizing rubber tyre aggregates in concrete mixtures. The research aims to provide insights into the potential benefits and challenges associated with this innovative approach, promoting eco-friendly construction practices. The study quantifies the environmental benefits, emphasizing the sustainable nature of this approach. This study stands out for its holistic evaluation of the use of waste rubber tyre aggregates in high-performance concrete. The combination of mechanical, durability, and environmental assessments provides a comprehensive understanding of the potential benefits and challenges, making it a unique contribution to the existing body of knowledge. In conclusion, the research signifies the viability and sustainability of incorporating waste rubber tyre aggregates in high-performance concrete, offering a promising avenue for advancing environmentally friendly construction practices.
