Clinker is a critical component in the production of cement. It is a nodular material, usually in the form of small marble-sized pellets, produced by heating limestone, clay, and other raw materials in a kiln at extremely high temperatures. The intense heat causes chemical reactions, resulting in the formation of clinker, which is then finely ...

The Bogue composition is calculated from the oxide composition of the cement or clinker, based on the molecular weights of the oxides. 3-The CaO must be corrected for the amount which is combined with SO3 in CaSO4 and the uncombined free CaO. ∴ %CaOCombined = %CaO – SO3*56/80 – Free CaO. %CaOCombined = %CaO – SO3*0.7 – Free CaO.

Typical GA dosage rates used during grinding of clinker vary from 0.01% to 0.15% of the manufactured cement mass. After the grinding process, GAs may not preserve their original molecule structures; however, they do remain adsorbed onto the cement particles to entail variations of cement properties whether in the fresh or hardened states.
