ABSTRACT

This work aims at incorporating industrial wastes arising from the metallurgical sector, as fillers into polymeric resins. The waste materials that were investigated are: brass foundry sand, ferrous slag, inert steel aggregate for construction, white slag from steelmaking ladle secondary treatment, electric arc furnace dusts and aluminum anodizing wastewaters treatment sludge. Two different types of resins were used: a thermoset phenolic resin normally used for the manufacture of foundry molds and a thermoplastic aqueous dispersion vinyl-based resin generally used for soils stabilization and retaining dust. The selection of the most suitable resin for each residue depends on the characteristics of the resins and the waste particle size: for powder residues, it was used a vinyl-based resin, whereas for larger particle size residues a phenolic resin has been employed. Samples were prepared by compression molding of parts at room temperature and characterized for mechanical properties, water absorption and leaching.
