Life Cycle Assessment of Mortars Produced Partially Replacing Cement by Treated Mining Residues

The use of secondary mining resources to replace conventional constituents in mortars production has proved the effectiveness preserve quality mechanical, physical, and chemical properties. However, minimal research been performed quantify environmental impacts with residues. In present work, a life cycle assessment 10 was carried out. A reference mortar (100% cement binder) substitutions 10%, 25%, 50% by raw, electrodialytic treated, plus thermal treated residues were analysed. studied six categories: (1) abiotic depletion; (2) global warming; (3) ozone (4) photochemical creation; (5) acidification; (6) eutrophication potentials. results demonstrated that formulated raw may decrease impacts, namely warming potential (55.1 kg CO2 eq./t modified mortar). Considering treatments applied residues, major mitigations reported creation (−99%), depletion (−76 −98%), acidification (−90 −94%), mainly due disposal avoided comparison mortar. Analysing all mortars’ their management options, products showed higher influence (18 52%). Coupling procedure, contributed for 99% mortars.
