Fly Ash Used To Increase Strength Of Concrete - CEMEX UK,
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.
