Effect of mining residues treated with an electrodialytic

Dec 01, 2020 A higher amount of cement in mortar composition leads to an increase of volume in this porosity range, attributed to the clinker phase (Santos et al., 2020). Other authors reported the same trend (Arizzi and Cultrone, 2013), which may also be justified by a higher water retention by the mortars with mining residues during short term hydration.
