2021-6-4 Two types of ashes are produced as a result of the incineration process: bottom ash and fly ash. Out of the total MSW ash, bottom ash constitutes 75–80% of the total combined ash stream and is difficult to use as SCM (Li et al., 2012). But MSW fly ash is used as SCM in cement (Siddique, 2010). It is a grey to black amorphous, glass-like

T. Hemalatha, Ananth Ramaswamy, in Handbook of Fly Ash, 2022 18.1 General. Blended fly ash (FA) cement can be produced either by intergrinding the FA with Portland cement clinker during manufacturing, called postpozzolana cement, or by blending the dry FA with ordinary Portland cement (OPC) on-site. The characteristics of blended FA cement vary depending upon the
