Jun 27, 2017  Class F fly ash can be used when blended with lime, portland cement or cement kiln dust (CKD). Typical proportions for the Class F fly ash lime blends are two to eight percent lime blended with 10 to 15 percent Class F fly ash. Also, 0.5 to 1.5 percent Type I portland cement can be blended with Class F fly ash to produce the stabilizing agent.
