Characteristics and Properties of NCC Portland Pozzolana Cement:

  • Portland Pozzolana cement plays a very important role in making cement paste PPC plays a role in making cement paste, plastic and malleable (for doing internal and external finishes.
  • PPC reduces the heat generated from the first phase of water is added.
  • It reduces cement permeability in plain and enforced concrete.
  • It improves the plastic and bonding feature of cement grout (to be suitable for plastering).
  • It acts as a heat insulator (it reduces electric power consumption used for lighting and air conditioning).
  • It has the property of absorbing any noise and helps in reducing sound echoing, that is, it has an excellent acoustic property.
  • It increases fire resistance (due to that Pozzolana has silica and alumina, this type of cement tolerates high temperatures during fires; thus, we see that furnace chimneys are made of PPC.)
  • It has a high resistance sulfates, chlorides and acids.
  • It has a high resistance to interaction of alkalis with silicate.
  • It reduces porosity and permeability and increases the surface of the granules.
  • It reduces cement permeability in plain and enforced concrete.
  • It has high sulfate resistance (All construction works and buildings done along coastal areas or on on soil rich with dissolved sulfate).
  • It has an overtime resistance to weathering conditions (Actually, archaeological monuments and historical sites are built of rocks of a volcanic origin. A living testimony is the presence of old Roman palaces).
  • It reduces the high temperature generated by high C3S content.
