Product information
CEM I 52.5R
HIGH STRENGTH CEMENT RECOMMENDED FOR CONCRETE AND CONCRETE PREFABS
BULK
MAIN APPLICATIONS
- High strength concrete
- Reinforced concrete
- Prestressed concrete and precast and prestressed structural elements
- Concrete for rapid removal of formwork, uncasing and demoulding
- Shotcrete
- Self-compacting concrete
MAIN USAGE RESTRICTIONS
- Reinforced and mass concrete in big volumes
- Compacted dry concrete
- Concrete with alkali-reactive aggregates
PRECAUTIONS
- Store in a watertight and dry place
- Store preferably for less than a month
- Take care of the dosage, mixing and curing to avoid desiccation
- Check temperature during mixing and curing in order to avoid shrinkage cracks during the first curing hours and the loss of rheology of fresh concrete
- Do not mix with gypsum or other type of cement
