Considering the production of a tremendous amount of construction and demolition waste (CDW) worldwide, it is necessary to develop new-fashioned and sustainable methodologies for the value-added upcycling of these wastes. In that context, this study focused on the utilization of CDWs in geopolymer production. Besides, the effects of different types of industrial wastes on the mechanical and fresh properties of CDW-based geopolymers were investigated. The designed blends containing different types of CDWs (hollow brick, red clay brick, roof tile, glass, and concrete wastes) and industrial wastes (fly-ash, slag, and silica fume) were activated by different combinations of NaOH and Ca(OH)2. The concrete waste was used as fine aggregate. Flow table, buildability, and vane shear tests were performed for fresh property assessments. Besides that, the mechanical performance of geopolymer mixtures was evaluated by conducting compressive strength tests. Results showed that CDW-based precursors have the potential to be used in geopolymer production for valuable recycling. The incorporation of industrial wastes into the CDW-based geopolymer mixtures caused an enhancement in the workability. In addition, the mechanical properties of the CDW-based geopolymer mortars were improved with the inclusion of industrial wastes. It is believed that the findings of this study will contribute to the current literature by proposing a different way of producing novel CDW-based geopolymers in favor of sustainability.
