Assiut Portland Pozzolanic Cement
Assiut Portland Cement
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 A-P (42.5)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.
