CEM I 52,5 R

Cement for concrete with special properties

Portland cement CEM I 52,5 R is produced by grinding of portland cement clinker with addition of optimal quantity of gypsum as a setting time regulator.

Moravacem d.o.o recommends this type of cement for prestressed elements and structures, for concrete elements where fast demolding is required and production of high strength concrete in general.


  • PC 52,5 R
  • CEM I 52,5 R

Designation, composition and cement quality are in accordance with Rulebook on cement quality

Properties of CEM I 52,5 R

  • High early and final strengths
  • Provides faster construction making production costs lower
  • Compatible with chemical admixtures
  • Provides efficient utilization of chemical admixtures which results in enhanced properties of fresh and hardened concrete (lower Wc ratio, improved consistency, resistance to frost and salts…)
  • Optimal fineness
  • Uniform light color
  • Uniform quality

Application of cement CEM I 52,5 R

  • Production of prestressed structures and elements, reinforced concrete elements which require fast demolding (prefabricated structures, bridge girders, railway sleepers)
  • Production of high-performance concrete (HPC), compressive strengths > 70MPa
  • Production of concrete precast elements (poles, curbs, pipes)
  • Production of concrete paving elements
  • Production of lightweight concrete products
  • Suitable for production of ordinary concrete in winter conditions
  • Can be used also for production of dry mixes for mortars and construction adhesives

Properties of concrete made with CEM I 52,5 R

Moravacem had conducted previous concrete tests with cement CEM I 52,5 R. Based on results of these tests, following conclusions were made:

  • designed and tested concrete trials have good workability;
  • regarding compressive strengths, concrete trials fulfilled designed concrete classes;
  • resistance of concrete to combined frost and salts impact with CEM I 52,5 R is achieved with air entraining agents and good aggregates quality;
  • strengths up to 45 MPa, with good workability are achieved with CEM I 52,5 R even without concrete chemical admixtures;
  • strengths over 45 MPa, with good workability are achieved with CEM I 52,5 R with concrete chemical admixtures for water reduction and workability improvement;
  • HPC (High Performance Concrete), concrete with strength over 70 MPa, can be achieved with application of concrete chemical admixtures for water reduction and workability improvement followed by good aggregates quality;
