Cement-based mortars production applying mining residues treated with an electro-based technology and a thermal treatment ; Technical and economic effects
The authors acknowledge the Portuguese Foundation for Science and Technology (FCT) for the support given to CENSE and CERIS through the strategicprojects UIDB/04085/2020 and UIDB/04625/2020. J. Almeida PhD fellowship PD/BD/135170/2017 from the EcoCoRe Doctoral program. The authors thank Ana Paula Menezes from LNEC for the samples TGA/DTA analysis, Professor José Mirão from Hercules laboratory for the XRD assistance, Eng. Manuel Pacheco from Panasqueira mine for providing mining residues samples and Eng. Vítor Silva for the support during mortar formulations and mechanical tests. ; The combination of treatments may improve the extraction of toxic and critical elements from secondary resources, produce changes in materials’ physico-chemical properties and improvements on the sustainability of strategies. Mining residues were treated with an electrodialytic process alone or coupled with a thermal procedure, and reused in cement-based mortars by replacing 10, 25 and 50% of the cement binder content. This study demonstrated the technical and economic feasibility of mortars produced with treated mining residues, namely in applications where flexural strength is key factor. The mechanical properties of the mortars corroborated their compatibility with bedding mortars and fired brick masonry walls. ; authorsversion ; published
