A new method, Dynamic Leaching Test (DLT), was put forward to analyse the leaching behaviour and leaching mechanism of heavy metals in solidification body of municipal solid waste incineration (MSWI) fly Ash. In this study, two groups of solidification materials were used, one with ordinary Portland cement (C), and the other with slag-and-clinker (SC). In each solidification body, solidification material/ (solidification material + MSWI fly ash) weight ratio was 25% and water/solid weight ratio was 0.3. After a 60-day curing period, DLT was app...
