Fly ash is used in about 50% of ready mixed concrete (PCA 2000). Class F fly ash is often used at dosages of 15% to 25% by mass of cementitious material and Class C fly ash is used at dosages of 15% to 40% by mass of cementi-tious material. Dosage varies with the reactivity of the ash and the desired effects on the concrete (Helmuth 1987 and

Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick.
