Pozzolanic Portland Cement

The pozzolanic cement produced at Kavan Boukan conforms to Iranian National Standards No. 3432 and 1-17518.
Using high-quality Type 2 clinker in production not only ensures compressive strength but the pozzolan content reduces heat of hydration and increases durability, especially in environments containing sulfates and sometimes chlorides.
Comparison of compressive strength results with the Iranian standard highlights the high quality of Kavan Boukan pozzolanic cement, which obtained the standard mark at the early production stage.

Producing pozzolanic Portland cement with high-quality specifications provides broad and diverse properties and applications, making it one of the superior products of Kavan Boukan Cement Factory.

Key Features of Pozzolanic Portland Cement

  • Moderate resistance to sulfate attack in sulfated environments.
  • Suitable for general use in mortar or concrete.
  • 28-day compressive strength of 450 ± 20 kg/cm².
  • Early-age compressive strength is low, reaching optimal strength after 28 days.
  • Enhances concrete strength.
  • Cost-effective and economical.
  • Micro-silica fills capillary pores, creating dense and impermeable concrete.
  • Resistant to freezing and cold climates.
  • Reduces heat generation during cement hydration.
  • Minimizes surface cracking due to superior physical and chemical properties.
  • Significantly reduces concrete volume when used in large pours.
  • Pozzolanic use greatly reduces overall cement consumption in concrete.
  • Protects concrete materials and embedded rebar from corrosive substances.
  • High resistance to sewage and chemical exposure.
