ABSTRACT: The generation of
industrial residues is unavoidable, but these materials may be recovered,
redirecting them toward new production processes, rather than allocating them
to the stream of discards. The aim of this paper is to study the feasibility of
utilization of metallurgical wastes as raw material for tiles in the ceramic
industry, using the residual
materials as aggregates in clay based ceramics. The residues used are: sludge
and slag from several metallurgical processes, Ruthner dust and foundry sand. Samples
were obtained from mixtures of clay and each waste in various percentages,
which were then heat treated. The pieces obtained were characterized using
several techniques, with the aim of determining the properties of these
materials in relation to the commercial requirements. A high feasibility of
reuse of most of these wastes as raw material in the production of ceramic
bodies has been established.
