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

How Fly Ash Can Affect Concrete Color and Performance Fly ash in concrete is often misunderstood. Because it is a by-product from another industry, many contractors think of fly ash as "filler". They consider it to be simply a low-cost additive that allows the concrete producer to make higher profits while utilizing inferior materials.
Because fly ash is a byproduct of coal, which itself is full of heavy metals and toxins that can be dangerous, concern has been raised that buildings made from fly ash concrete could be harmful to people. The biggest challenge to fly ash came in 2008, following the massive fly ash spill at the Kingston Fossil Plant in Tennessee (see sidebar).
