China Fly Ash Beneficiation Unburned Carbon

The presence of the unburned carbon in fly ash will decrease the compressive strength of the cement. The standard specification of 1stgrade fly ash in China limits the loss-on-ignition LOI values less than 5 assuming that this parameter provides good estimation of carbon content. However, the LOI of most.
