  • Uses, Benefits, and Drawbacks of Fly Ash in Construction

    UsesClassificationPropertiesBenefitsDurabilityFly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement. Road construction projects using PCC can use a great deal of concrete, and substituting fly ash provides significant economic benefits.

  • 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.

  • FLY ASH CONCRETE - WHAT ARE THE REASONS FOR

    Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix. The main benefit of fly ash for concrete is that it not only reduces the amount of non-durable calcium hydroxide (lime), but in the process converts it into calcium silicate hydrate (CSH), which is the strongest and most durable portion of the paste in concrete.
