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.
