CLINKER

Clinker is a product sintered at 1450 degrees Celsius of limestone - clay and some coefficient adjusting additives such as iron ore, bauxite, sand...

The main chemical composition of the mixture includes 04 main oxides such as: CaO (from limestone), and SiO2, Fe2O3, Al2O3 (from clay). If lacking, they will be supplemented with the above adjustment additives.

04 main oxides in the mixture when heated to 1450 degrees Celsius will react with each other to form 4 main minerals in clinker C3S (3CaO. SiO2); C2S(2Cao.SiO2); C3A (3CaO.Al2O3); C4AF (4CaO. Al2O3. Fe2O3)

These minerals have different crystal structures that determine the properties of clinker. The quality of clinker will determine the properties of cement.

With the strength of being located in areas with high quality raw materials, Hoang Long believes that we can provide the best clinker that meets ASTM standards (USA) to produce the ideal quality cement.
