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.

Coal Bottom Ash for Portland Cement Production

 · The specific surface Blaine of the cement was 4,050 m 2 /kg; fineness of the collected coal fly ash was 3,976 m 2 /kg. The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (5–8% residue on 45 μ m sieve).

Fly Ash

 · Fly ash is known as a supplementary cementitious material, or SCM. The use of SCMs dates back to the ancient Greeks who incorporated volcanic ash with hydraulic lime to create a cementitious mortar.
