| Abstract |
In the current research, clay-based bricks with beneficial utilization of industrial "scrap-soil" as admixture were developed and characterized, in order to contribute to circular economy, environmental protection and conservation of natural resources. "Scrap-soil" is an industrial soil containing residues of steel scrap and/or steel making by-products as a result of their temporary storage in open steel industry soil spaces. Brick-shaped specimens were formed by extrusion of clay/"scrap-soil" mixtures in various proportions up to 9 % wt. industrial soil, and then fired at different peak temperatures (850-1100 degrees C). Shrinkage and weight loss upon sintering as well as bulk density, porosity, mechanical strength and thermal conductivity of sintered ceramic microstructures were determined and studied as a function of the admixture percentage and firing temperature. The experimental results confirm that incorporation of "scrap-soil" into standard red ceramic bodies is feasible, as their shape, density, mechanical performance and thermal conductivity remain practically unaffected with increasing the admixture percentage. Moreover, the sintering temperature can be optimized either to obtain specific characteristics of the brick bodies or to attain energy savings. |
