fly ash used in cement manufacturing

Cement with Fly Ash. Fly ash is recovered in the form of a fine dust by the dust collectors of furnaces burning pulverized coal. Fly ash may be siliceous (consisting mostly ofeactive silicon dioxide(SiO2) and aluminium oxide (AI2O3) with pozzolanic properties) or calcareous (consisting ofreactive calcium oxide(CaO),reactive silicon dioxide(SiO2) and aluminium oxide (AI2O3 ) and having both pozzolanic and …

    Fly ash can only be activated when cement is being used as well. When cement reacts with water, it produces lime, which reacts with fly ash, which produces CSH (Hydrated Calcium Silicate). The CSH is the same cementing product as Portland cement. Fly ash will usually range between 15-30% of the cement when being used.
