Highlights The reactivity of MSWI bottom ash is similar to that of Class F coal fly ash. Thermodynamic modeling can guide the mix design of MSWI bottom ash-based AAM. Excessive leaching of MSWI bottom ash containing cement and AAM can be prevented. Recommendations are provided for using MSWI bottom ash as SCM and AAM precursor.
Abstract This work evaluated the reactivity and leaching potential of municipal solid waste incineration (MSWI) bottom ash as supplementary cementitious material (SCM) and precursor for alkali-activated materials (AAM). The chemical composition of the amorphous phase in MSWI bottom ash was found to be in the same range as that of Class F coal fly ash. The reactivity of MSWI bottom ash as SCM and AAM precursor was tested to be much lower than that of blast furnace slag, but similar to that of Class F coal fly ash. The method of thermodynamic modeling was found useful in providing references for the mix design of MSWI bottom ash-based AAM. Grinding MSWI bottom ash into powder for the application of SCM and AAM precursor increased its leaching potential. Based on the findings of this study, recommendations were provided on how to use MSWI bottom ash to prepare blended cement pastes and AAM.
