The Disadvantages of Fly Ash in Concrete Hunker

Fly ash is a byproduct from coal-fired power plants that is frequently used as an admixture in concrete to replace a portion of the Portland cement. Using fly ash in concrete is environmentally beneficial because it reduces the Portland cement (a major contributor of CO2) required in concrete. Fly ash in concrete improves performance in some ways, but it also has some disadvantages.
