There are some varieties in cement that always find good demand in the
market. To know their characteristics and in which area they are most
required, it will be better to take a look at some of the details given
Blast Furnace slag cement (PBFSC):
The rate of hydration heat is found lower in this cement type in
comparison to PPC. It is most useful in massive construction
projects, for example - dams.
Resisting Portland Cement:
This cement is beneficial in the areas where concrete has an
exposure to seacoast or sea water or soil or ground water. Under any
such instances, the concrete is vulnerable to sulphates attack in
large amounts and can cause damage to the structure. Hence, by using
this cement one can reduce the impact of damage to the structure.
This cement has high demand in India.
Hardening Portland Cement:
The texture of this cement type is quite similar to that of OPC.
But, it is bit more fine than OPC and possesses immense compressible
strength, which makes casting work easy.
Portland Cement (OPC):
Also referred to as grey cement or OPC, it is of much use in
ordinary concrete construction. In the production of this type of
cement in India, Iron (Fe2O3), Magnesium (MgO),
Silica (SiO2), Alumina (AL2O3), and Sulphur trioxide (SO3)
components are used.
Pozolona Cement (PPC):
As it prevents cracks, it is useful in the casting work of huge
volumes of concrete. The rate of hydration heat is lower in this
cement type. Fly ash, coal waste or burnt clay is used in the
production of this category of cement. It can be availed at low cost
in comparison to OPC.
Made of iron, coke, limestone and iron scrap, Oil Well Cement is
used in constructing or fixing oil wells. This is applied on both
the off-shore and on-shore of the wells.
Produced at the temperature of about 1400 to1450 degree Celsius,
clinker cement is needed in the construction work of complexes,
houses and bridges. The ingredients for this cement comprise iron,
quartz, clay, limestone and bauxite.
It is a kind of Ordinary Portland Cement. The ingredients of this
cement are inclusive of clinker, fuel oil and iron oxide. The
content of iron oxide is maintained below 0.4% to secure whiteness.
White cement is largely used to increase the aesthetic value of a
construction. It is preferred for tiles and flooring works. This
cement costs more than grey cement.
from these, some of the other types of cement that are available in
India can be classified as:
early strength cement
Portland Cement (OPC)
is manufactured in the form of different grades, the most common in
India being Grade-53, Grade-43, and Grade-33. OPC is manufactured by
burning siliceous materials like limestone at 1400 degree Celsius and
thereafter grinding it with gypsum.
·Ordinary Portland Cement-Grade 43: Having been certified with IS
8112:1989 standards, Grade 43 is in high demand in India and is largely
used for residential, commercial, and other building construction
purposes. It has a compressive strength of 560 kg per square cm. Today
OPC 43 is most widely available in Gujarat through an extensive
Portland Cement-Grade 53: Having been certified with IS12269:1987
standards, Grade 53 is known for its rich quality and is highly
durable. Hence it is used for constructing bigger structures like
building foundations, bridges, tall buildings, and structures
designed to withstand heavy pressure.
such, Ordinary Portland Cement is used for quite a wide range of
applications. Some of the Ordinary Portland applications are in
pre-stressed concrete; dry-lean mixes, durable pre-cast concrete, and
ready mixes for general purposes. The chemical components of Ordinary
Portland Cement are Magnesium (MgO), Alumina
(AL2O3), Silica (SiO2), Iron (Fe2O3), and Sulphur trioxide (SO3).
Ordinary Portland Cement is in great demand
in India and will continue to be used in Indian infrastructuralupgradation and other constructions.
Pozzolana Cement is manufactured by blending
pozzolanic materials, OPC clinker, and
gypsum either grinding them together or separately. Today Portland Pozzolana
Cement is widely in demand for industrial and residential buildings,
roads, dams, and machine foundations.
is an important ingredient in PPC which is commonly used in the form of:
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:
ash - IS 3812:1981
clay - IS 1344:1981
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.
