-The main chemical composition of the mixture consists of 04 main oxides such as: CaO (from limestone), and SiO2, Fe2O3, Al2O3 (from clay), if lacking, will be supplemented with the above adjustment additives.
- 04 main oxides in the mix when heated to 1450 degrees C will react together to form four main minerals in clinker C3S (3CaO. SiO2); C2S (2Cao.SiO2); C3A (3CaO.Al2O3); C4AF (4CaO. Al2O3. Fe2O3)
These minerals have different crystal structures and determine the properties of the clinker The quality of the clinker determines the properties of the cement.
used in the production of building materials.
