Hydraulic conductivity of fly ash-amended mine tailings
The objective of this study was to evaluate the effect of fly ash addition on hydraulic conductivity (k) of mine tailings. Fly ash-amended mine tailings have potential application as construction materials in active mines, transportation earthworks, and other geotechnical engineering projects. Addition of cementitious binder (fly ash) to mine tailings has the potential to reduce hydraulic conductivity and enhance contaminant sequestration to be feasible in earthwork projects. Mine tailings used in this study were categorized as synthetic tailings and natural tailings. Natural tailings were ...
