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
