Both recycled coarse aggregates (RCA) and recycled fine aggregates (RFA) are firstly used to fully replace the natural coarse and fine aggregates in the concrete mix design. Later, the cement rich ultrafine particles, recycled glass powder and mineral fibres recovered from construction and demolition wastes (CDW) are further incorporated at a smaller rate either as cement substituent or as supplementary additives. Remarkable properties are noticed when the RCA (4–12 mm) and RFA (0.25–4 mm) are fully used to replace the natural aggregates in a new concrete mix. The addition of recycled cement rich ultrafines (RCU), Recycled glass ultrafines (RGU) and recycled mineral fibres (RMF) into recycled concrete improves the modulus of elasticity. The final concrete, which comprises more than 75% (wt.) of recycled components/materials, is believed to be the most sustainable and green concrete mix. Mechanical properties and durability of this concrete have been studied and found to be within acceptable limits, indicating the potential of recycled aggregates and other CDW components in shaping sustainable and circular construction practices.11883386enginfo:eu-repo/semantics/openAccessjournal article10.1016/j.conbuildmat.2020.121697Recycled aggregatesRecycling concreteConstruction and demolition wastesCircularitySustainabilityRecycled glassMineral fibersMineral additionsRecycled aggregatesRecycling concreteConstruction and demolition wastesCircularitySustainabilityRecycled glassMineral fibersMineral additionsCivil and Structural EngineeringBuilding and ConstructionGeneral Materials ScienceSDG 12 - Responsible Consumption and ProductionProject IDinfo:eu-repo/grantAgreement/EC/H2020/723582/EU/Cost-Effective Recycling of CDW in High Added Value Energy Efficient Prefabricated Concrete Components for Massive Retrofitting of our Built Environment/VEEPinfo:eu-repo/grantAgreement/EC/H2020/723582/EU/Cost-Effective Recycling of CDW in High Added Value Energy Efficient Prefabricated Concrete Components for Massive Retrofitting of our Built Environment/VEEPFunding InfoThe authors wish to acknowledge the financial support from EU Horizon 2020 Project VEEP ‘‘Cost-Effective Recycling of C&DW in High Added Value Energy Efficient Prefabricated Concrete Compo-nents for Massive Retrofitting of our Built Environment” (No.723582).The authors wish to acknowledge the financial support from EU Horizon 2020 Project VEEP ‘‘Cost-Effective Recycling of C&DW in High Added Value Energy Efficient Prefabricated Concrete Compo-nents for Massive Retrofitting of our Built Environment” (No.723582).http://www.scopus.com/inward/record.url?scp=85098122490&partnerID=8YFLogxK
