Characteristics:

  • high sulphate resistance due to considerable part of slag (low hydration temperature, reduced tendencies of shrinking and creation of cracks),
  • considerable increase of pressure strength with higher age of concrete (after 28 days),
  • longer start of bonding,
  • possible thermal treatment in start phase of manipulation increasing the early strength,
  • considerable slower diffusion of aggressive ions, 
  • increased resistance to affect of clean and aggressive water.

Recommendation for use:

  • construction in wet and aggressive environment enriched with sulphates,
  • work in road constructions, construction of bridge footers (naval and coastal objects),
  • underground works, stabilization and injection of the ground,
  • system for treatment of sewage water,
  • drainage sewage systems,
  • watering systems etc..

 Esspecialy adequate for:

  • objects in aggressive environments,
  • massive constructions with large area and volumes and
  • concrete work in hot climate (hot period).

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.

Certificates:

  • This product has a valid certificates according HRN EN 197-1,BAS EN 197-1:2002
  • Declaration ofConformity for CEM III/B-32,5 N SR- LH according BAS EN 197-1:2002 and rulebook about technical performances for cement issued by “Fabrika cementa Lukavac d.d” (class number of declaration 071/13 from 04.02.2013)
