Fly Ash Used To Increase Strength Of Concrete | CEMEX UK

Fly Ash is a by-product of coal-fired electric generating plants. The coal is pulverized and blown into burning chambers for immediate combustion. Heavier ash particles (bottom ash or slag) fall to the bottom of the burning chamber and the lighter ash particles (Fly Ash) fly out with the exhaust gas, thus the term Fly Ash.
