Cement for the preparation of concrete with highly demanding concrete constructions.
Specifically adapted for load-bearing concrete structures and for concretes of higher finishing strengths.

Description

Mixed Portland cement contains: 65-79 % Portland cement clinker, 21-35 % silica fly ash of mark V from the power plant and limestone of a mark L, as main ingredients, milled together in a ball mill with the addition of natural gypsum as a regulating binding agent. The certificate of conformity to specifications: HRN EN197-1 i HRN EN197-2, BAS EN 197-1, BAS EN 197-2.

Benefits and Characteristics

  • GOOD WORKABILITY
    Good workability, colour-fastness, small changes in volume
  • HIGH HEAT OF HYDRATION
    High heat of hydration enables concreting in colder environments
  • STANDARD INITIAL STRENGTH DEVELOPMENT
    Standard development of initial strength minimises a risk of cracking during construction
  • GOOD RESISTANCE
    Good resistance to moderately aggressive effects due to the addition of silicon fly ash.

Recommended for:

  • Production of concrete of higher strength class;
  • Portable armoured and unarmed concrete structures (foundations, walls, beams, panels, arches, staircases etc.);
  • Production of transportable and pumped concrete;
  • Concrete structures of large section and volume;

Transport and Storage

Delivered in bags weighing 25 kg (1.4 t on a pallet) and 50 kg (1.5 t on a pallet).

With proper transport and storage, cement should be used no later than 6 months from the date of production.

Bagged cement should be stored in a dry place protected from atmospheric precipitation, above ground on a pallet or other dry substrate.
