Fineness of Cement

Finer cement offers a greater surface area for hydration and hence faster the development of strength. The fineness of grinding has increased over the years. But now it has got nearly stabilized. Different cements are ground to different fineness. The particle size fraction below 3 microns has been found to have the predominant effect on the ...

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

results in imprecisions in determinations of the surface area. Thus, AM is a scaling factor that describes the (relative) change in solid surface area induced by filler addition in comparison to the surface area provided by a unit mass (1 g) of cement. In other words, AM is the surface area of filler per unit surface area of cement in the system.
