The fineness of cement is a property that must be carefully controlled during the manufacturing process. The total specific surface of the cement represents the surface area available for hydration.
The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined.
