英文摘要	The utilization of polymer stabilizers is a promising method in mitigating bauxite residue (red sand) dust pollution. Its thickening property can effectively bind sand particles by constructing crusts to withstand wind erosion. Previous studies recommended the mixture of polymer solutions for a better dust control performance. However, limited references discussed the effects their viscosity on the structure strength of formed crusts and the final erosion resistance. The environmental adaptability of polymer mixtures was also rarely investigated. Thus, this paper investigates the effect of relationship between polymer viscosity, environmental adaptability and the final dust control performance. Results illustrated that the applied polymers have excellent ability in withstanding wetting, high temperature and long-term UV exposure, which indicates a broad applicability in wet conditions and desert regions. For both single cationic polymers or polymer mixtures containing cationic polymers, higher solution viscosity resulted in better crust strength and dust erosion resistance when applied on red sand surface. Thus, the viscosity of polymer mixtures solution can effectively predict the structure strength of formed crust and the final erosion resistance of treated sand. (C) 2019 Elsevier B.V.
