Cement offer OPC 42.5 N

Cement grade OPC 42.5 N

OPC 20S 42.5N (Ordinance on the quality of the cement)             EN 197-1 standard

Cement is a hydraulic binder, finely ground inorganic material that is mixed with water creates a paste, which is long enough to retain workability and then hydration reaction. After hardening, retains the strength, stability and appropriate volume. Because of these characteristics it is widely used in construction as a basic ingredient of concrete and mortar.

Cement PC 20S 42,5N or CEM II / AS 42,5N the portland cement with slag containing 80-94% of clinker and 6-20% slag.

Properties:

  • Stable quality (water consumption, setting time, strength in all periods);
  • Bright color of cement is suitable for combination with pigments
  • Optimum start and end binding
  • Slower development of heat of hydration
  • Excellent workability characteristics
  • Resistant to aggressive environments (effect of sulfate water, chlorides and other salts);
  • Resistant to frost
  • The ability to achieve high strength concrete.
