Portland Pozzolana Cement - Fly Ash & Calcined Clay Based | Enhanced Workability Improved Water-tightness Reduced Lime Leaching

By efficiently understanding the market trends we are able to manufacture and supplied an portland pozzolona cement in Macherla Andhra Pradesh India. it is very Useful for general construction works and especially suitable for works in aggressive environmental conditions employed for water retaining structures marine works mass concreting such as dams dykes retaining walls foundations and sewage pipes.

Portland Pozzolana cement utilizes two types of pozzolanas:

a) Fly ash - Covered under IS 1489 (part I)

b) Calcined clay - Covered under IS 1489 (part II)

PPC with fly ash as Pozzolana is more popular in the country owing to the easy availability of quality fly ash from modern coal based thermal power plants.

Portland Pozzolana cement is manufactured either by inter-grinding Portland cement Clinker with gypsum and fly ash obtained from thermal power plants or by intimately blending OPC and fly ash.

The percentage of fly ash in PPC permitted by IS: 1489 varies from 15 per cent (minimum) to 35 percent (maximum).

PPC accounts for nearly 47 per cent of the cement produced in the country

PPC provides improved workability has less segregation and bleeding increased water-tightness and reduced tendency of lime to leach out
