Fly Ash

Fly ash is a by-product of the combustion of pulverised coal in the furnace of a coal fired power station boiler. Fly ash is extracted from the exhaust gases of the boiler by way of bag filters which then leaves relatively clean air to be vented to the environment. The captured fly ash is classified to produce grade 1 fly ash that is stored in silos ready for delivery by bulk tanker into the market. Fine grade fly ash is widely used as a cementitious material in premix concrete, mortars, cement based products and grouts.
