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
