Cement for concrete plants CEM II/A-L 42,5 R

CRH Serbia, in order to meet the market demand, is producing high performance cement intended for concrete plants.
With the aim to satisfy specific requirements related to modern building industry and interest of our customers, i.e. concrete producers, construction companies, as well as other consumers of bulk cement, CRH launched production of this particular cement type.

Types

  • PC 20L 42,5 R
  • CEM II/A-L 42,5 R

Cement quality codes and standards

This product  was created, not only to meet the requirement to achieve uniform quality and high early strengths, but also to achieve compatibility with chemical additives.

 

Cement CEM II/A-L 42,5 R – properties

  • High early strengths
  • Uniform quality
  • Light-coloured
  • Optimum beginning and end of binding
  • Reduced and slower hydration heat development in comparison with CEM I
  • Low alkali content
  • Uniform standard strength
  • Suitable for preparation of high-strength concrete types
  • Excellent compatibility with the following types of additives:
    • plasticizers
    • superplasticizers
    • air entrainers
    • accelerators and retarders modifying the setting time
    • accelerators of the hardening process
    • sealants which increase concrete water impermeability
    • materials used for cold weather concreting

Properties of concrete made with  CEM II/A-L 42,5 R

  • increased impermeability
  • frost-resistant
  • extended durability
  • faster concstruction
  • wide range of concrete types
    • for concrete types up to MB 40 of plastic consistency, no chemical additives like plasticizers or superplasticizers are needed
    • concrete types over MB 40 with good workability, compactness and water impermeability, as well as with increased resistance to the impact of aggresive waters, are obtained after the addition of  plasticizers and superplasticizers.
  • With addition of superplasticizers which retard the intial setting time of concrete, the time needed for transport of fresh concrete is significantly extended, which should be attested by previous trials
  • Good workability with a reduced water-cement ratio, which adds to better strength and reduced concrete shrinkage
  • Reduced concrete shrinkage and easier curing in comparison to concrete types made with CEM I, due to reduced hydration heat

Application of concrete made with  CEM II/A-L 42,5 R

  • Traditional and pumped concrete
  • Water impermeable concrete
  • Frost resistant concrete
  • Frost and salt resistant concrete
  • Sprayed concrete
  • Self-compacting concrete
  • Concrete for self-levelling cementitious screeds
  • Diverse constructions made of plain and reinforced concrete for construction of residential, office and industrial buildings, bridges, tunnels, etc.
  • Road construction
  • Production of precast concrete construction components and other products made of concrete
  • Production of dry mortars
