Jaypee produces a wide variety of cements, which are
specifically designed to cater to the customer’s requirements for
different types of cements in each of its markets. All the brands, which
the Company produces, are so evolved in their characteristics and
properties that they will surpass BIS Standards. For each brand, the
relevant BIS standards are mentioned in enclosed table along with a
comparison with the BIS requirement.
The state-of-the-art cement plants operated by the Jaypee Group are
equipped with the most modern technology from the globally leading
technology providers. Extensive Instrumentation & fully automatic and
computerized process control system, custom designed Quality Control
software like QSO Expert and CADES in the Mines, Cross Belt Expert
Analyser using the Prompt Gamma Neutron Activation Analysis - for the
first time in India, X-Ray Fluorescence and X-Ray Diffraction analysers
and optical microscope, enable production of cement of the highest quality
consistently on a sustained basis. Jaypee Rewa Plant Quality control
laboratory is accredited laboratory from National Accreditation Board for
Calibration & Testing Laboratories, for chemical and mechanical Cement
testing.
All brands are marketed in attractive HDPE bags, containing 50 Kgs of
quality cement from Jaypee. Bags are identified with a conspicuous Jaypee
Logo, which also over the years has come to be regarded as a “Hallmark” of
quality.
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) 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. |
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. |

| Jaypee
Cement (OPC-53 Grade) |
OPC-53 Grade has been the mainstay for fast
paced construction of high strength, heavy load bearing
Structures viz., Bridges, prestressed elements, penstocks,
precast elements etc. requiring very high strength to
negotiate the heavy static & dynamic loads.
Jaypee Cement (OPC-53 Grade), because of its fine nature,
good particle size distribution, optimal phase composition,
imparts the properties of higher strength to the structures.
The Chemical & Physical properties of Jaypee Cement (OPC-53
Grade) surpasses the properties of OPC 53 grade as defined
in IS: 12269 – 1987. (Please Refer Table – 3) |

One of the very few cement
manufacturers having the potential to manufacture this
special grade of super fine cement which due to its
enhanced quality and performance parameters has been
approved by the RDSO of Indian Railways for manufacture
of “RAILWAY SLEEPERS”.
Jaypee Cement (OPC-53 S Grade) is also used in
heavily loaded or pre stressed structures, which are
subjected to high dynamic loads due to rapidly moving
volumes, be it a train passing on the railway sleepers
or a great volume of water moving at high speed to
generate electricity in a penstock. The characteristics
of Jaypee Cement (OPC-53 S Grade) vis a vis the
prescribed BIS Standards IS: 12269 – 1987 can be seen in
