    The intersection of digital transformation and circular construction practices presents significant potential to mitigate environmental impacts through optimised material reuse. We propose a five-step (D5) digital circular workflow that integrates these digital innovations towards reuse, validated through real-world case studies. We assessed a variety of digital tools for enhancing the reuse of construction materials, including digital product passports, material classification assisted by artificial intelligence (AI), reality capture, computational design, design inspired by generative AI, digital fabrication techniques, extended reality, and blockchain technology. Using action research through a multiple case study approach, we disassembled several buildings that were set for demolition and subsequently designed and executed construction projects using the salvaged materials. Our findings indicate that digital transformation for detection, disassembly, distribution, design, and finally deployment significantly support the application of circular economy principles. We demonstrate the potential of the proposed workflow for industry implementation and scalability.
  • Durability performance of concrete incorporating carbonated recycled coarse aggregates: a review

    Carbonation of recycled coarse aggregates (RAs) has drawn significant attention in recent years. This study shows that most durability indicators of carbonated RAs concrete (cRAC) are lower than natural aggregate concrete, while compared to concrete with non-carbonated RAs, all durability indicators of cRAC are improved by 13–55% because of the densified microstructure after carbonation. Optimized carbonation methods (i.e., adjusting moisture content and using biomaterials) are suggested to improve the quality of carbonated RAs further.
