When the ball milling time is increased to 45 min, the coarse BA is further crushed and refined, and the d 50 decreases from 26.3 μm to 13.2 μm. It is close to fly ash particle size, but it is still larger than the latter. Further increasing the ball milling time, the proportion of fine particles will continue to increase.
