| Abstract: | In this paper, the chemical and mineralogical compositions of municipal solid wastes incineration (MSWI) fly ash was studied. The effects on setting time and mechanical properties of cement pastes containing the MSWI fly ash were investigated. Several important aspects, including microstructure and hydration products of cement pastes, toxicity and solidification mechanism of heavy metals in hardened cement pastes were analyzed and discussed by using different ways such as SEM, XRD and ICP. Moreover, we studied the possibilities of developing the MSWI fly ash into a kind of new cement mixture. |
