Cement-based mortars production applying mining residues treated with an electro-based technology and a thermal treatment: Technical and economic effects

Research output: Contribution to journalArticle

Abstract

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.
