Notation in cement chemistry

Clinker: Cement chemistry notation. Cement chemists use a form of notation which, at first sight - and maybe second or third sight - may seem a little odd. Oxides are referred to by their first letter: 'C' represents CaO; 'M' is MgO and so on, for all the oxides likely to be encountered in cementitious systems, as shown below. "Normal chemists ...

Cement chemist notation - Wikipedia

The cement chemist notation is not restricted to cement applications but is in fact a more general notation of oxide chemistry applicable to other domains than cement chemistry sensu stricto. For instance, in ceramics applications, the kaolinite formula can also be written in terms of oxides, thus the corresponding formula for kaolinite, Al2Si2O5(OH)4,
