Abstract

Recycled Aggregate Concrete (RAC) has emerged as a promising sustainable construction material, addressing both environmental concerns related to construction waste disposal and the depletion of natural resources. This review provides a comprehensive analysis of recent advancements in the preparation techniques and mechanical properties of RAC. It discusses the characteristics of recycled concrete aggregates (RCA), processing methods, mix design optimization, and various mechanical performance aspects including compressive strength, tensile strength, flexural behavior, and elastic modulus. Additionally, the review highlights the influence of different treatment methods on RCA properties and subsequent RAC performance, identifies current challenges, and suggests future research directions in this field.
