Variability of cement

However, of as much, if not more, importance as fineness is the particle size distribution of the cement; relying simply on surface area measurements can be misleading. Some minerals, gypsum for example, can sometimes grind preferentially producing cement with a high surface area, but very fine gypsum and relatively coarse clinker particles.

During the loading process, the clinker segregates and forms cones according to the particle size. A homogenous clinker mixture is, however, an essential condition for the performance of cement mills. Therefore, it is recommended to systematically shift the silo discharge gates in order to blend the different particle sizes in the silo.

Characterization of clinker with regards to reactivity

The produced clinker varies in reactivity depending on many factors as for example the quality of the limestone, the conditions in the kiln etc. If a more reactive clinker is produced, the clinker part in the cement could be more diluted. It would still have the same quality as the cement made of less reactive clinker but the CO. 2

The heating process produces chunks of PC called clinker. To produce commercial grade PC, the PC clinker is usually ground with a small amount of the calcium-containing mineral gypsum (CaSO 4 2H 2 O) to control the rate of setting (5.1.-5.3.). The PC composition and particle-size distribution determine how the material sets up after water is added.
