Article Synopsis
- * The study examines the leaching risk of heavy metals (Cr, Sb, Pb) from MSWI fly ash in BFS-based cementitious materials using various leaching methods and finds that the leaching concentrations remain below standard limits.
- * A specific mix (A4 matrix) demonstrates strong compressive strength and increased dissociation of blast furnace slag, enhancing hydration reactions and controlling long-term leaching risks, supported by simulation results on heavy metal states within the material.
The disposal of nonferrous metal tailings poses a global economic and environmental problem. After employing a clinker-free steel slag-based binder (SSB) for the solidification/stabilization (S/S) of arsenic-containing tailings (AT), the effectiveness, leaching risk, and leaching mechanism of the SSB S/S treated AT (SST) were investigated via the Chinese leaching tests HJ/T299-2007 and HJ557-2010 and the leaching tests series of the multi-process Leaching Environmental Assessment Framework (LEAF). The test results were compared with those of ordinary Portland cement S/S treated AT (PST) and showed that the arsenic (As) curing rates for SST and PST samples were in the range of 96.
