Sustainable Construction Materials: Evaluating the Performance and Environmental Impact of Recycled Aggregates in Concrete

Abstract

One of the most significant contributors to environmental degradation is the building industry. This is especially true when considering the enormous use of natural resources and the development of waste from construction and demolition. The use of recycled aggregates as a feasible alternative to conventional resources in the manufacture of concrete is becoming increasingly important in the context of tackling these difficulties. Sustainable construction practices are becoming increasingly crucial. This study examines the performance of recycled aggregates in concrete as well as their impact on the environment. Particular attention is paid to the mechanical qualities, durability, and ecological benefits of these recycled aggregates. The research investigates the similarities and differences between recycled aggregate concrete (RAC) and conventional concrete by means of an exhaustive experimental investigation. The characteristics that are evaluated include compressive strength, tensile strength, and water absorption. In addition, a life cycle assessment (LCA) is carried out in order to estimate the environmental benefits that are associated with the incorporation of recycled aggregates. These benefits include a reduction in carbon footprint, energy usage, and trash disposal. Based on the findings, it appears that recycled asphalt concrete (RAC) has the potential to achieve equal performance to conventional concrete while simultaneously reducing its impact on the environment. This discovery lends support to the widespread adoption of sustainable materials in the building industry. The findings of this study make a significant contribution to the expanding body of knowledge on environmentally responsible building methods and bring to light the potential of recycled aggregates as an essential component in the transition towards the creation of sustainable infrastructure.
