 This study, it found that fly ash can be used to replace some of the cement in order to increase the hydration rate of the cement paste, reduce its temperature, and improve its compressive strength. Additionally, it showed that mechanical activation of fly ash can enhance its reactivity and decrease its particle size, resulting in a denser structure and improve compressive strength.
