In some countries an off-white clinker, which gives a reflectance value over 70 when ground, is produced at a cost only a little over normal gray clinker. When this is blended with ground blast furnace slag (up to 60% depending on use and early strength) a cement with reflectance over 80 can be produced.

Clinker free lime (CaO f) should be as high as possible to avoid hard burning of clinker, but safely below value, inviting mortar expansion; normally, between 0.5% and 1.5%. Free lime indicates incomplete clinker burning, therefore should be monitored regularly and maintained closely in the acceptable range.

The grinding plant at a cement factory is used to reduce the particle size distribution of various materials such as raw meal, fuel or clinker to set parameters. In a sense, a grinding plant uses energy (through milling) to create fineness and it is the production personnel's aim to optimize the fineness with the production
