Potential Future Direction of The Sustainable Production of Precast Concrete with Recycled Concrete Aggregate: A Critical Review

Abstract

This critical review explores the incorporation of recycled concrete aggregate (RCA) in precast concrete within the context of sustainable construction. Amid the construction industry’s quest for eco-friendly alternatives, the integration of RCA in precast concrete has the potential to revolutionize it. This review highlights the many benefits of using precast concrete with RCA, such as faster construction, enhanced quality control, and reduced on-site disruptions. Examining the current applications of RCA in precast concrete, this paper critically evaluates its merits and drawbacks, shedding light on the complexities of this environment-friendly construction method. Further, this paper delves into how RCA contributes to sustainable energy and cleaner construction. It not only scrutinizes the existing practices but also proposes innovative ways to implement them, thereby fostering a more sustainable and environment-friendly construction industry. By examining new precast concrete technology, modeling, and sustainability, this review describes the transformative trends shaping both precast concrete and the construction sector. Advocating for the widespread adoption of RCA in precast concrete for sustainable construction, this review challenges established paradigms. It emphasizes the importance of adhering to industry standards and considering environmental and financial factors in achieving a more sustainable construction industry.
