    10/07/2017· This study investigates the potential approach of utilising CO 2 to produce carbonated fly ash (CFA) in a cement blend for new ‘green’ construction materials. The aqueous fly ash (FA) carbonation experiments are performed in a batch bench-scale reactor to study the effect of different CO 2 flow rates (of 2 and 4 ml/min) and water-to-FA ratios (15 and 7.5 ml/g) on the

  • Fly ash Wikipedia

    Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.
