Fly Ash Cement - Lehigh Hanson, Inc.

Fly ash is a pozzolan, virtually identical to volcanic ash. When used in concrete mixes, fly ash is known as a supplementary cementing material, or SCM. Fly ash is the most widely used SCM, and has been added to concrete since the 1930s. It can supplement cement on its own or used in conjunction with other SCM in blended cements.

Types of Fly Ash Products - CEMEX USA - CEMEX

Fly Ash. Fly Ash is a byproduct 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.
