  • 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 has also been used as embankment and mine fill, and it haSee more on thebalancesmb
