What Is Fly Ash Cement? (with pictures)

Dec 28, 2020· Fly ash cement is a primary ingredient in certain concretes that is often used as an alternative to Portland cement, which is a more traditional concrete base. The ash itself is a byproduct of coal combustion, but once formed into a cement the ash usually binds in such a way as to neutralize many of the chemicals and toxins that have made coal burning so controversial in recent years.
