Sustainable Utilization of Recycled Coarse Aggregate in Concrete: A Review of Key Properties and Applications

Bharti Ahirwar, Dr. Harsh Rathore

Abstract


Recycled coarse aggregate (RCA) concrete has gained considerable attention as a sustainable alternative to conventional concrete, contributing to resource conservation and waste reduction. This review synthesizes research on the characteristics, mechanical properties, and practical applications of RCA concrete. Key factors influencing RCA quality include the quantity and quality of adhered mortar and cement paste, impacting water absorption, strength, and durability. Studies reveal that RCA exhibits higher porosity, lower elastic modulus, and reduced compressive strength compared to natural aggregates. However, innovative mixing methods and treatments, such as double mixing and acid treatment, can enhance RCA performance. Additionally, incorporating supplementary materials like silica fume or steel fibers has proven effective in mitigating strength losses. The review also explores the potential of RCA in structural applications, demonstrating that with optimal design and quality control, RCA concrete can achieve satisfactory performance in various construction scenarios. Overall, this paper emphasizes the role of RCA in advancing sustainable construction practices and highlights areas for future research to maximize its utility.
