Jaypee produces & markets both Portland Pozzolana Cement (PPC) & all grades of Ordinary Portland Cement (OPC). A brief introduction of each brand is enumerated as below:-

PORTLAND POZZOLANA CEMENT

Jaypee Cement produces special blend of Portland Pozzolana Cement and markets it under the popular brand name ‘Jaypee Cement’ (PPC) .

JAYPEE CEMENT (PPC)

Jaypee Cement (PPC) is a market leader among all blended/composite cements in the markets of U.P, Bihar, M.P., Punjab, Haryana, Delhi & Nepal. Its unique design and blend, with high strength clinker and superior quality flyash has made it the popular cement for construction of large number of strong and durable structures in these states.

Fine particles of Jaypee Cement (PPC) when mixed with water readily form a smooth paste, which results in a smooth surface. When used with sand and aggregates it yields a very strong & durable concrete.
Jaypee Cement (PPC) helps to produce more cohesive concrete and mortar which is also less prone to segregation and bleeding. Due to this quality, Jaypee Cement (PPC) is suitable for any type of structural application.
*(Curing is done as per specified norms)

Use of superior quality flyash in Jaypee Cement (PPC) not only reduces the incidence of lime leaching from concrete and mortar but also results in refined pore structure, reduced permeability and long term strength gain. These attributes make the construction strong, compact, impermeable and resistant to chemical attacks.

Jaypee Cement (PPC) is being used for a number of applications like housing, commercial complexes, roads, wells, canals, dams etc. which establishes Jaypee Cement (PPC) as the preferred choice of the discerning customer. It is particularly well suited for the tropical climatic conditions of India.

Jaypee Cement (PPC) surpasses the requirements laid down by Bureau of Indian Standards (BIS) for flyash based PPC cement in IS:1489 Part (I):1991.

Qualities of Jaypee Cement PPC
Unmatched characteristics of Jaypee Cement (PPC) which form the basis of sound & durable construction are:

Better workability due to spherical shape of flyash particles and better slump retention.
Better pumpability – provides more cohesive concrete and mortar.
Superfine particles provide great finish to the structure.
Provides un-segregated concrete of better integrity.
Low heat of hydration.
Reduced shrinkage and swelling.
Better pore refinement, reduced permeability.
Better resistance to chloride and sulphate attack
Better resistance to alkali-silica reaction.
Resistance to corrosive attack on steel reinforcement.
Reduced lime leaching.
High compressive strength.
High modulus of elasticity especially at later ages.
Improved bondage of concrete to steel.
Long term strength gain.

Conclusion

Jaypee Cement (PPC) helps to produce better concrete & compressive strength keeps on growing with time. Jaypee Cement (PPC) promotes workability in fresh concrete even with less water and hence yields high strength concrete of low permeability, less bleeding, better pump-ability and superior finish. Hardened concrete made with Jaypee Cement (PPC) benefits from long term gain in compressive strength and related properties like low creep & shrinkage etc.

Furthermore, the concrete is very durable and effectively resists aggressive attack of sulphate and chloride ions. It is also resistant to Alkali aggregate reaction. The concrete is not subjected to attack by acid rain due to presence of green house gases (GHGs) in higher concentrations in atmosphere.
