Is prepared by grinding pozzolanic clinker with Portland cement. It is also produced by adding pozzolana with the addition of gypsum or calcium sulfate or by intimately and uniformly blending portland cement and fine pozzolana.
Ord. Portland Cement
Portland Pozzolana Cement
Rapid Hardening Cement
Low Heat Cement
Is prepared by maintaining the percentage of tricalcium aluminate below 6% by increasing the proportion of C2S. This makes the concrete to produce low heat of hydration and thus is used in mass concrete construction like gravity dams, as the low heat of hydration prevents the cracking of concrete due to heat.

Portland Pozzolana Cement
Rapid Hardening Cement
Low Heat Cement
Is used to reduce the risk of sulphate attack on concrete and thus is used in construction of foundations where soil has high sulphate content. This cement has reduced contents of c3A and c4AF.
White Cement
Air Entraining Cement
Sulfates Resisting Cement
High Alumina Cement
It is produced by mixing 5-10% mineral pigments with ordinary cement. They are widely used for decorative works in floors.
White Cement
Air Entraining Cement
Red Cement
Colored Cement
It is most widely used type of cement which is suitable for all general concrete construction. It is most widely produced and used type of cement around the world with annual global production of around 3.8 million cubic meters per year. This cement is suitable for all type of concrete construction.
