  • Ultrafine Fly Ash Precast concrete

    Ultrafine fly ash can be added along with the normal dosage of fly ash and will disperse throughout the mix. Typical dosages of ultrafine fly ash will range from 8 percent of total cementitious to as high as 12 percent depending on the particular performance desired. In a high-strength application, the typical additional rate is 8 percent to 9
