Blast Furnace Cement

CEM III / A 42,5N

A type of cement that generates low heat of hydration. This product is produced using selected raw materials (GGBS) confirming EN 15167-1 which is following a strict quality control system. This gives a consistent end product to conform finally with the requirements of EN 197-1/2011 and ES 4756-1/2022.


Produced according to Egyptian standards ES 4756/1-2022 and complies with European specifications EN 197/1-2011.

Physical characteristics:

Cement Standard Specifications Limits​

Initial setting time (min) ≥ 60
Soundness (expansion) mm ≤ 10
Compressive strength 2D (Mpa) ≥ 10
Compressive strength 28D (Mpa) ≥ 42.5

Chemical Characteristics:

Cement Standard Specifications Limits​

Sulphate (SO3)  ≤ 3.5 %
Chloride content (CL-)  ≤ 0.1 %

Target Market:

  • Ready mix companies
  • General contractors
  • Precast companies
  • Pre-blending companies


  • When large cross sections and mass concrete is applied, such as bridges, dams, skyscrapers, and rafts, because it has reduced the heat of hydration (less than 210 KJ/Kg) which reduces cracks.
  • Where high compressive strength is required
  • Concrete works subjected to aggressive soils or ground water and where high sulphate exposure is expected, such as in coastal areas and used also in sewage systems.
