- This research deals with the optimization of concrete mixtures, fully based on Construction and Demolition Wastes (CDW) aggregates and Portland cement, suitable for structural applications and developed in the European project RE4 (REuse and REcycling of CDW materials and structures in energy efficient pREfabricated elements for building REfurbishment and construction). The objective was to formulate concrete compositions, using 100% of CDW aggregates, in compliance with requirements for industrial production of prefabricated building elements (e.g. beams, columns, foundations, stairs, slabs, panels, partitions). Concretes of strength class C25/30 and C32/40 and suitable consistency have been designed and produced on lab scale. Technical performance (e.g. consistency, compressive strength, density) of concretes have been evaluated according to specific standards and, therefore, their suitability for industrial scaling up has been assessed. At this stage of the Project, selected concretes formulations are used for industrial production of prefabricated elements, intended for installation on real-scale demo- buildings located in different European climatic regions.
