Morphological behavior Effect of fly ash content. With respect to the morphological analysis, one of the first conclusions reached was that, as a consequence of processing, ash particle size decreased. However, in the composites, generally, a small number of large particles still existed (which can be critical-sized flaws). ...

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.
