CEM II/B-S 42.5N
With a mineral additive content of up to 36%, it reduces the carbon footprint by 10% compared to Portland cement. This feature makes it both construction-friendly and environmentally friendly, supporting greenhouse gas reduction. It contributes to sustainability with features such as stable performance, high fineness (filling effect), improved workability, and high slump retention performance, equivalent to the strength and durability performance of Portland cement (CEM I 42.5 R). It also offers benefits like low hydration heat (especially suitable for mass concrete and hot weather applications).

Precautions for Use
- Must be used according to specified minimum cement dosage and maximum water/cement ratio standards.
- Proper protection and curing process must be applied according to standards.
- Concrete poured into molds should not have molds removed before reaching sufficient mechanical strength.
- Long-term transport of ready-mix concrete should be avoided.
- Measures should be taken to prevent crack formation during concrete pouring in hot and windy weather conditions.
Not Recommended for Use
- It is not recommended to use it alone without mineral additives (ground blast furnace slag, fly ash, etc.) in environments exposed to sulfates and harmful chemicals.
- It is not recommended to use it alone without mineral additives (ground blast furnace slag, fly ash, etc.) in concretes requiring low hydration heat and mass concrete.
Environment, Safety, and Storage
- Use appropriate protective clothing, gloves, eye, and face protection equipment.
- Request detailed safety information from the “Safety Data Sheet” of the product.
- Bulk cement should be stored in appropriate silos protected from moisture and wind, while bagged cement should be stacked in moisture, wind, and cold-protected storage areas, stacked no more than 10 layers high.
