Fly Ash

Eskom utilizes pulverized coal combustion to fire their boilers. 90% of Eskom’s ash is classified as fly ash. Fly ash, also known as pulverised fly ash, is the fine dust that is produced from the combustion process of the finely pulverised coal in the boiler fire system. Fly ash can be obtained directly from a boiler unit ash bunker through an agreed written arrangement. This option may require infrastructure development, but please contact Eskom to enquire about options.

Uses & benefits:
 
Fly ash in the building and construction industry is widely applied where it is used as a cement extender (blended cements) or an ingredient in its own right in concrete (supplementary cementations material). Fly ash can be used as functional filler in plastics and rubber. Its particle shape aids processing and reduces the amount of polymer required.
