CONCRET CEMENT Fly ash cement contains up to 40% fly ash under ASTM standards or 35% under standards. Fly ash is pozzolanic, to maintain maximum strength. Since the addition of fly ash allows for a lower water content of the concrete, the initial strength can also be maintained. Where good quality cheap fly ash is available, it can be an economical alternative to ordinary Portland cement.
