摘要: Abstract A laboratory research program was initiated to assess the environmental suitability of highway embankment structures built with high carbon fly ash and C-type ashes. Two different leaching tests, water leach tests (WLTs) column (CLTs), were conducted study boron (B), manganese (Mn), molybdenum (Mo), selenium (Se) from soil/fly mixtures. The results indicated that an increase in content increased pH effluent solutions generally leached metal concentrations significantly. mass metals WLTs higher than those CLTs few exceptions. It concluded had great effects on B, Mn, Mo, Se yielded Mo while it caused a decrease Mn aqueous solutions. Fe2O3 Al2O3 contents ashes decreased no significant effect B observed. Unburned did not have direct leaching.
