Abstrakt: Reusing aggregate from building and demolition waste can help protect the ordinary natural aggregate supply, reduce landfill demand, and drive toward a more sustainable environment. This paper examines the recycled history of recycled aggregate and recycled aggregate. A general review of how recycled aggregates were used by previous researchers in recent years and their findings are reviewed in this review paper. In addition, methods for enhancing the mechanical characteristics of recycled aggregate and long-term efficiency such as improving the properties without modifying the recycled aggregate (namely, different concrete mixing designs and the addition of reinforcing fibers) were reviewed. The machine learning model for predicting compressive strength in addition to compressive stress modulus and graphs for recycled aggregate concrete are reviewed, as well as their limitations are discussed. It discusses the research perspectives of recycled aggregate, namely the development of "green" processing methods for recycled aggregate and additional guidance on building a database to predict the strength of recycled aggregate.
