The global construction industry, a colossal consumer of natural
resources and a significant generator of solid waste, is under immense pressure
to transition from a linear "take-make-dispose" model to a Circular
Economy (CE). A cornerstone of this transition is the utilization of Recycled
Concrete Aggregates (RCA) derived from construction and demolition (C&D)
waste in new Reinforced Cement Concrete (RCC) structures. This paper provides a
comprehensive review of the performance evaluation of RCA in RCC, analysing its
fresh, hardened, and durability properties. It further investigates the
multifaceted economic impact, moving beyond simple cost accounting to encompass
life-cycle costing, carbon pricing, and market creation. Crucially, this review
integrates modern paradigms, exploring the role of Artificial Intelligence (AI)
and Machine Learning (ML) in optimizing RCA mix designs and predicting
performance. Finally, it bridges the gap between technical feasibility and
practical implementation by discussing the financial models, risk management
strategies, and business management shifts required for widespread RCA
adoption. The synthesis concludes that while technical challenges persist, they
are surmountable, and the true key to unlocking RCA's potential lies in a
synergistic approach that combines advanced material science, data-driven
decision-making, and innovative business and financial management.
