Fly Ash Used To Increase Strength Of Concrete - CEMEX

Fly ash is the fine ash produced at coal-fired power plants that develops cementitious properties when mixed with cement and water. Fly Ash is a pozzolan, meaning it is a siliceous and aluminous material that, in the presence of moisture, will combine with the lime liberated during the hydration of cement to form cementitious materials. Where does it come from? Fly Ash is
