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.
Characteristics
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
Applications:
- 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.
