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 ...

CEMENT RAW MATERIALS - International Cement Review
and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.
Cement Manufacturing Process: What is Cement made of.
Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions
Chapter Two Types of Cement - University of Technology, Iraq
The rapid strength development of this type of cement is achieved by grinding the cement to a very high fineness: 7000 to 9000 cm. 2/g. Because of this, the gypsum content has to be higher (4 percent expressed as SO3). Because of its high fineness, it has a low bulk density. High fineness leads to rapid hydration, and
