Our interest in Assiut Cement Company - CEMEX is to reduce pollution and carbon emissions resulting from the manufacturing and use of cement. The company took the lead in developing its Assiut cement product to CEM II / B-P (32.5 N), aiming to use materials with pozzolanic properties with clinker, in line with Egyptian and international specifications. Pozzolana improves the properties of cement and concrete by reducing the reaction temperature and cracks, as it reduces the porosity of the concrete.

Uses and applications

  • It can be used in all types of constructions.
  • It is suitable for concrete elements of large cross sections (mass concrete).
  • Suitable to be used in the hot weather.

Advantages

  • It gives high final compressive strength (28 days). 
  • It gives more workability for the concrete.
  • It reduces concretes cracks.
  • Suitable to be used in hot weather.
