PORTLAND-COMPOSITE CEMENT CEM II/B-M (V-LL) 32,5 R

COMPOSITION OF CEMENT

  • Portland clinker cement in an amount of 65-79%
  • silica fly ash and limestone with a total of 21 - 35%
  • calcium sulphate as a setting time regulator

PROPERTIES

  • density 2,80 kg/dm3
  • bulk density 1,35 t/m3
  • moderate strength growth dynamics
  • moderate heat of hydration
  • good workability and plasticity of concrete mix
  • optimal time of the concrete mix working properties maintenance
  • very good adhesion to the substrate (a significant reduction in the need of hydrated lime use for the production of mortars and plasters - a reduction of mortar production costs)
  • low shrinkage

FIELD OF APPLICATION

  • normal freight concrete according to PN-EN 206-1
  • cement and cement-lime mortars: "masonry and plastering"
  • concrete for large and small-sized precasted elements
  • "lean" concrete for the foundation of supporting structures

CEMENT SATISFIES THE REQUIREMENTS OF:

  • EN 197-1:2011 "Cement - Part 1: Composition, specifications and compliance criteria for common use cements" standard.
  • EN 197-2:2014 "Cement - Part 2: Conformity assessment" standard.
