An experimental study on the effects of drying-wetting cycles to the mechanical properties of red mud (opens in new tab)

Red mud, a hazardous industrial waste generated during alumina production, faces great challenges in safe stacking and utilization due to its complex chemical composition and poor engineering properties. Long-term stacking of red mud is accompanied by repeated natural drying-wetting cycles, which significantly alter its strength characteristics and further threaten the stability of red mud stockpiles. In this study, Bayer red mud (BRM) and mixed red mud (MRM) from the No.5 stockpile of Guizho...
