Pozzolana is an important ingredient in PPC which is commonly used in the form of:
  • Fly ash
  • Volcanic ash
  • Silica fumes
  • Calcined clay
PPC is resistant to harsh water attacks and prevents the formation of calcium hydroxide at the time of cement setting and hydration. It withstands aggressive gases, thermal cracks, wet cracking, etc. The BIS quality specifications for Pozzolana materials used in PPC have been mentioned below:
  • Fly ash - IS 3812:1981

PPC is used in heavy load infrastructure and constructions such as marine structures, hydraulic structures, mass concreting works, plastering, masonry mortars, and all applications of ordinary Portland cement.

Shudh cement has 5 percent of the market share and is available abundantly in Gujarat, penetrating all 3 - primary, secondary, and tertiary markets. Some of the other big names in the Portland Pozzolana manufacture are Ultratech, Ambuja, ACC cements, Star Cement, and Birla group.
