Recycled red mud as an useful geotechnical materialPavšič, Primož (Avtor) Đurić, Marija (Avtor) Košir, Mateja (Avtor) Mauko Pranjić, Alenka (Avtor) Mladenovič, Ana (Avtor) Oprčkal, Primož (Avtor) Seršen, Sara (Avtor) Zalar Serjun, Vesna (Avtor) red mudrecyclinggeotechnical compositesenvironmentRed mud (RM) is an extractive waste from Bayer process in alumina production. The most conventional methods of RM disposal are tailing dams, or dry storage,both of which raiseenvironmental concerns due to the high alkalinity of RMandthe presence and leaching of potentially hazardous elements (PTEs).Due to its fine-grained nature and poor mechanical properties, as well as leaching of potentially hazardous substances, RM cannot be used by itself. Properties of the RM can be improved, by mixing it with hydraulic or pozzolanic binders, such as calcareous ashes or steelmaking slag, to produce mechanically stable and durable composites for earthworks. On the other hand, RMcan also serve as an immobilization additive for remediation of contaminated soils.Two different approaches for useful utilization of RMare presented based on results of laboratory research and a real case study, opening of new possibilities for conserving natural resources and reducing environmental hazards of RM deposits.CRC Press20242024-10-30 06:47:09Neznano20754sl© 2024 the Authors
