The NIST cement hydration microstructural model and experimental studies are used to investigate the effects of particle size distribution and water-to-cement ratio on hydration kinetics.

Too small of a media size or too large of one can decrease the mill efficiency, making the media size dependable on the ground particle size. That is, in the case of a particle size below 10 μm, finer media sizes were more effective, and when the media sizes were between 1.7 and 1.2 mm, efficient grinding was performed [ 24 ].
