CEM I 52.5 R
Portland cement with high initial strength
The main components of this cement according to BDS EN 197-1 are: clinker from 95 to 100%, and additional components from 0 to 5%. Calcium sulfate is added to adjust the setting time.
Use: According to the instructions of the concrete or mortar designer. Recommended temperature for work with cement: 5 to 30°C. Lower temperatures retard cement setting, while higher temperatures accelerate it.
- bridges, viaducts, channels, etc.
- reinforced concrete and prestressed structures
- monolithic structures in civil and industrial construction
- production of dry mixes
- aerated concrete
- self-compacting concrete.
