Abstract: The growing demand for sustainable construction materials has led to increased research on recycled aggregate concrete (RAC) as an alternative to conventional concrete. This study explores the development of RAC by replacing natural aggregates with recycled aggregates derived from construction and demolition waste. Various mix designs, treatment methods, and admixtures are analyzed to enhance the mechanical & durability properties of RAC. The structural stability of RAC is assessed through compressive strength, tensile strength, flexural strength, and durability tests. Additionally, factors such as water absorption, shrinkage, and bond strength are examined to evaluate its long-term performance. Finite element modeling (FEM) and experimental investigations are employed to compare RAC’s behavior with traditional concrete under different loading conditions. Results indicate that with proper treatment and mix proportioning, RAC can achieve mechanical properties comparable to conventional concrete while promoting sustainability and reducing environmental impact. The study concludes that RAC is a viable structural material for non-load-bearing and certain load-bearing applications, contributing to sustainable construction practices.
