Portland cement CEM I 52,5 N specially suitable for exeptional demanding and high value projects.

Characteristics:

  • high development of hydration heat,
  • very fast development of strength.

Recommendation for use:

  • production of prefabricated concrete elements and products and prestressed concrete constructions,
  • production of special kinds of masonry and plastering as well as construction-chemical products,
  • demanding construction projects with demand on high mechanical resistance of the concrete construction, high early strength and early mechanical stress of the construction,
  • production of concrete, highly resistant on wear-out, frost and salt.

Transportation and storage:

  • to be transported in resources that protect cement from humidity influence,
  • transport resources must be cleaned from other materials that may affect the quality of the cement,
  • storage in concrete or steel silos that protect cement from outer influences, especially from humidity,
  • during storage in silos insure avoidance of mixing the cement with other products,
  • with adequate transport and storage, cement should be used the latest, within 6 months from delivery,
  • cement can irritate eyes and skin and can cause heavy breathing,
  • it is necessary to avoid contact with eyes and skin and use personal protective equipment ,..
