Previously, an optimum concrete mixture using both MSWI residues as aggregates was formulated. A compromise between the environmental behaviour and the economy of the process was considered. Unconfined compressive strength and abrasion resistance values were measured in order to evaluate the mechanical properties. From these results, the granular mixture was not suited for certain applications owing to the high BA/APC content and low cement percentages used to reduce the costs of the final product. Nevertheless, the leaching test performed showed that the concentrations of all heavy metals were below the limits established by the current Catalan legislation for their reutilization. Therefore, the material studied might be mainly used in embankments, where high mechanical properties are not needed and environmental safety is assured.32 p.application/pdfeng(c) Elsevier Ltd, 2013Materials de construccióPropietats mecàniquesProtecció ambientalMatèria condensadaConstruction materialsMechanical propertiesEnvironmental protectionCondensed matterinfo:eu-repo/semantics/article6169612013-04-16info:eu-repo/semantics/openAccess
