x 0 is closely related to the difference between the properties of the center particle and that of the medium. It decreases with the decrease of the difference. With the hydration of cement and the pozzolanic reaction of fly ash, the properties of the medium are improved, and x 0 decreases. At the same time, the unreacted fly ash particles become smaller, and S increases.
