CEM II/B-M(V-L)42.5R

CEMENT RECOMMENDED FOR CONCRETE AND PREFABRICATED ELEMENTS

PACKED AND BULK

MAIN APPLICATIONS

  • Mass concrete
  • Reinforced concrete
  • Structural prefabs
  • Concrete for rapid removal of formwork, uncasing and demoulding
  • Self-compacting concrete
  • Concrete with alkali-reactive aggregates

MAIN USAGE RESTRICTIONS

  • Reinforced and mass concrete in big volumes
  • Emergency repair concrete

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
