Abstract: As an eco-friendly building material, recycled aggregate concrete (RAC) has gained widespread application in engineering fields such as road construction and building structures due to its effective utilization of waste resources, shortened production cycles, reduced costs, and significant reduction in environmental impact, making it a crucial approach to addressing the excessive consumption of building materials. In light of this, this paper focused on the preparation methods, mechanical properties, and current state of engineering applications of RAC. It systematically reviewed the methodologies for the full-process preparation and performance optimization of RAC, providing an in-depth analysis of the intrinsic mechanisms that enhance its mechanical properties, and summarized its current application status in engineering practice. Furthermore, this paper prospected future research directions for RAC, aiming to provide valuable references for its large-scale research and application.

Key words: recycled aggregate concrete, preparation method, strengthening technology, mechanical property, engineering application
