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.
