CEM I 42,5 R


  • cement of high strength class with high initial strengths


  • it is suitable especially for extreme strength intensive structures, concretes of higher quality grades C 30/37 – C 45/55, prestressed concretes C 30/37 – C 35/45, reinforced concretes, concrete products, prefabricates and wherever rapid mould removal is needed within 24 hours
  • it allows concreting even in cold and freezing environments, below the temperature of 5°C, where it can be processed using special additives
  • due to the higher development of heat of hydration, it is not suitable for large-volume concreting

Method of delivery:

  • bulk - road tankers, railway wagons of RAJ type
