  • Coal Bottom Ash for Portland Cement Production

    AbstractIntroductionMethod and MaterialsResults and DiscussionsConclusionsAcknowledgmentsBecause of industrialization growth, the amount of coal power plant wastes has increased very rapidly. Particularly, the disposal of coal bottom ash (CBA) is becoming an increasing concern for many countries because of the increasing volume generated, the costs of operating landfill sites, and its potential hazardous effects. Therefore, new applications of coal bottom ash (CBA) have become an interesting alternative to disposal. For instance, it could be used as a Portland cement constituent leading to more
  • What Is Fly Ash Cement? (with pictures) - wiseGEEK

    Coal Burning BasicsUses in ConcretePotential to Reduce ContaminationInvestigations Into Overall Environmental ImpactWhen coal and waste are burned in power plants, they create a non-combustible byproduct called coal ash. Two distinct types of ash particles make up coal ash: bottom ash, which collects on the bottom of coal furnaces, and fly ash, which is caught in the smokestacks as it "flies" up and away. The vast majority of the non-combustible material is fly ash, which travels up in the flue gas and gets caught in the smokestacks and chim在wisegeek上查看更多信息
  • Why use Fly Ash and Slag in Concrete? - Bay-Lynx ...

    The CSH is the same cementing product as Portland cement. Fly ash will usually range between 15-30% of the cement when being used. Since fly ash is finer than Portland cement, it will inhabit even smaller voids than cement particles, which are normally inhabited by water. This therefore aids in creating a stronger concrete with less permeability.
