“…Fluctuations in slag composition and availability may also contribute to the low usage [23]. Therefore, the use of steel slag in cement applications has been the topic of several studies, such as shown in the Chen et al's work [24]. They used combined physical pre-treatments; such as grinding, sieving, and magnetic separation for the recovery of iron rich materials and to use the remainder of the waste slag, from an integrated steel mill for the clinker production.…”

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.

“…The immobilisation/stabilisation of pollutants and the valorisation of hazardous industrial wastes is an area of great environmental and economic interest (Chen et al, 2010;Cruz-Yusta et al, 2011;Puertas et al, 2008;Yan et al, 2011). This paper describes the stabilisation and valorisation of waste ilmenite mud, generated in the titanium dioxide industry, as a component of sulphur polymer cement (SPC) that could be used in concrete construction works.…”

This paper reports the preparation of sulphur polymer cements (SPCs) incorporating waste ilmenite mud for use in concrete construction works. The ilmenite mud raw material and the mud-containing SPCs (IMC-SPCs) were characterised physico-chemically and radiologically. The optimal IMC-SPC mixture had a sulphur/mud ratio (w/w) of 1.05 (mud dose 20 wt%); this cement showed the greatest compressive strength (64 MPa) and the lowest water absorption coefficient (0.4 g cm−2 at 28 days). Since ilmenite mud is enriched in natural radionuclides, such as radium isotopes (2.0·103 Bq kg−1228Ra and 5.0·102 Bq kg−1226Ra), the IMC-SPCs were subjected to leaching experiments, which showed their environmental impact to be negligible. The activity concentration indices for the different radionuclides in the IMC-SPCs containing 10% and 20% ilmenite mud met the demands of international standards for materials used in the construction of non-residential buildings
