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.

Effort has been done to reduce the production of coal fly ash or to extract potentially valuable products from coal fly ash, such as cenospheres. Cenospheres are light, low density, thin-walled hollow ceramic microsphere with unique properties. Conventional cenosphere production methods involve the separation of cenospheres from coal fly ash.

BOTTOM ASH. Most bottom ash results from the burning of pulverized coal in suspension in the modern utility boiler used in coal-fired power plants. The heavier ash particles fall to the bottom of the boiler (bottom ash) and the lighter particles remain in the gas stream and are usually collected in an electrostatic precipitator as fly ash.

In this project, fly ash was used to mitigate potential ASR deteriorations that could otherwise occur due to use of siliceous glass aggregates. Prior research on natural siliceous aggregates (e.g., opal) has shown that ASTM C618 fly ash can be effective in controlling ASR expansions (Thomas 2011); however, it is not clear how fly ash mitigates ASR.
