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.

The specific surface Blaine of the cement was 4,050 m 2 /kg; fineness of the collected coal fly ash was 3,976 m 2 /kg. The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (5–8% residue on 45 μm sieve).. Several coal fly and ground coal bottom ashes were mixed in the laboratory using a powder mixer.
