This type of cement is produced in accordance with the specifications set out in the Iranian national standard number ISIRI-389 and the American standard ASTM-C150 and is produced as a modified Portland cement. Its special use is in the manufacture of concretes with moderate hydration temperature They were a necessity.

 Use in corrosive and humid environments, in contact with groundwater and running water

 Suitable for foundations, offshore structures and structures in highly corrosive environments

 In relatively bulky concretes, foundations, irrigation canals

 With the advantage of high resistance against sulfate invasion for the construction of concrete pipes, water and sewage canals

 Durability of concrete in adverse environmental conditions
