CEM I 52,5 R

 

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.

Applications:

  • 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.  

Delivery: bulk
