Sustainable transformation of fly ash industrial waste into …

Fly ash is a by-product of coal burning in coal-fired power plants. It is estimated that FA constitutes up to 75% of the total ash content in coal ( Goodarzi, 2006 ). The composition of FA mainly consists of silicate compounds with a small fraction of unburnt carbon/char ( Hower and Mastalerz, 2001 ).
