With the development of waste recovery techniques, previous research has revealed that coarse fractions municipal solid incineration (MSWI) bottom ash (BA) after proper treatment could be applied in construction sector, while fines are seldom recovered practice and normally landfilled. This study explores potential application fine MSWI BA (0–2 mm) as a supplementary cementitious material (SCM) Portland cement (PC) mixtures. Mechanical chemical pre-treatment approaches have been designed with various conditions to optimize treating process. The mineralogical compositions, well metallic Al content were characterized before pre-treatment. It was found both methods effective removing BA, Moreover, derived from mechanical exhibited more contribution hydration reaction PC mixtures, by amount products mineral phases formed hardened trial obtained further partially blended mortars evaluate performance compared SCMs inert fillers. treated resulted slight retarding effect on kinetics. Treated behaved better than coal fly contribute strength development, inclusion did not lead significant influences workability.
