title: Contribution to the sustainable management of resources by novel combination of industrial solid residues into red ceramics.
abstract: Limited amounts of industrial residues are recycled while the remaining huge quantities are stockpiled or disposed of, thus frequently leading to soil contamination. The utilization of industrial residues as valuable secondary resources into ceramics can contribute to efficient waste management and substitution for massive amounts of natural resources (clayey minerals) demanded for ceramic production. The low cost of these residues and even possible energy savings during mixture firing may also be beneficial. In the present study, the innovative combination of lignite fly ash with steel-making dust into clay-based red ceramics is undertaken, to contribute both to sustainable use of resources and prevention of soil contamination. Brick specimens were shaped by extrusion and fired, their microstructure was examined and the effect of the mixture composition and firing temperature on physico-mechanical properties was determined. Ceramic microstructures were successfully obtained by a suitable combination of fly ash with steel dust (5 + 5 wt%) into clays. Properties can be predicted and tailored to meet the needs for specific applications by appropriately adjusting the mixture composition and sintering temperature.
