Transforming mining wastes into alternative cementitious materials
The mineral residues from mining industry have potential to be used as secondary raw materials for alkali-activated materials (AAM) with the purpose for alternative cementitious materials. Mining waste-based AAMs were produced by alkali activation of mechanochemically activated mine tailings and mining waste rock. Two synergies with metakaolin and blast furnace slag were investigated to better understand the chemical and physical effects of mine tailings in the alkali-activated co-binder systems.
