Deurali PPC Cement

Deurali PPC Cement

Portland cement clinker, synthetic pozzolana (fly ash), and gypsum or calcium sulfate are ground together to create Portland-pozzolana cement. Fly ash is an extremely fine particle that is formed as a residue when coal-fired thermal power plants’ exhaust gases are electrostatically or mechanically precipitated.

The best PPC cement in Nepal is often made by combining and grinding 65-75% Portland clinker, 3-6% gypsum, and 15-25% fly ash.

Benefits of PPC

  • Water resistance due to concrete with high density.
  • Ultra fine particles give a firm grip to the building structure.
  • Improves the performance of concrete.
  • Reduces flow.
  • Reduces heat of hydration and prevents incisions.
  • No need for cement silica.
  • High resistance against sulfate and chloride.
  • Alkali reaction resistant.
  • High modulus of elasticity especially later ages.
  • Low volume (shrinkage & swelling) change previnting cracks.
