  • Why use Fly Ash and Slag in Concrete? Bay-Lynx

    Fly ash can only be activated when cement is being used as well. When cement reacts with water, it produces lime, which reacts with fly ash, which produces CSH (Hydrated Calcium Silicate). The CSH is the same cementing product as Portland cement. Fly ash will usually range between 15-30% of the cement when being used.


    coal ash properties & impact on clinker quality. dear ted. is there any good impact when we use lignite as a fuel instead of other solid fuels with low ash content. as i have seen on net that flyash from lignite gives lime in the range of 20%. if it is 20% than this flyash can be used as a source of lime in raw mix. please explain me in detail
