AB The construction sector is presently among the most resource-intensive industries, drivinga substantial body of research dedicated to the development of more sustainable materials to addressthese demands. A particularly promising approach within the framework of the circular economy isthe repurposing of waste as a principal raw material for the creation of new construction products.Within this context, the primary aim of this study is to engineer ceramic materials for brick productionusing 100% waste-derived inputs, specifically aggregate washing sludge and manganese miningby-products. To evaluate the potential of these sustainable ceramic materials, an extensive investigationwas conducted, encompassing both physical and mechanical testing, as well as a thoroughcharacterisation of the waste inputs. For this purpose, a series of ceramic specimens were fabricatedwith varying proportions of mining residues and aggregate washing sludge, adhering to the conventionalprotocols employed in the manufacture of ceramic bricks. The results demonstrate thatthese sustainable ceramics exhibit a linear shrinkage reduction of up to 5% compared to traditionalclay-based ceramics. Furthermore, they show water absorption levels—whether via capillarity, coldwater, or hot water absorption—that are up to twice those observed in conventional clay ceramics,while maintaining comparable density values. This increased absorption, however, correlates witha reduction in mechanical strength at higher concentrations of manganese waste, yet the materialcontinues to meet the minimum strength requirements as specified by industry standards for suchproducts. In conclusion, this research introduces a novel, sustainable ceramic material that not onlyreduces economic and environmental costs but also adheres to the required performance criteria forconstruction applications.
