Types Of Cement
  • 1. Rapid Hardening Cement (RHC)
  • 2. Portland Pozzolana Cement (PPC)
  • 3. Portland Slag Cement  (PSC)
  • 4. White Cement
  • 5. Ordinary Portland Cement (OPC)

Rapid Hardening Cement
Rapid Hardening Cement is s kind of cement which
achieves strength very fast.
5
The strength achieved by Rapid Hardening Cement
in 3 days is equivalent to the strength achieve
by Ordinary Portland Cement (OPC) in 7 days.
The Hardening properties of cement are enhanced
with the addition of 56 of Tricalcium Silicate.
The improved early strength is achieved by the
fineness of cement.
6
Advantages and Uses
It gains high strength in the early days and the
formwork can be removed earlier as compared to
other types of cement.
It requires a short period of curing.
Rapid hardening cement is used in areas like road
pavements so that the traffic can be opened
early. It is also used in manufacturing precast
slabs, posts, electric poles, concreting in cold
countries.
7
There is a reduced shrinkage during curing and
hardening of cement.
Rapid hardening cement is resistant to sulphate
attacks.
Rapid hardening cement is used in areas like road
pavements so that the traffic can be opened
early. It is also used in manufacturing precast
slabs, posts, electric poles, concreting in cold
countries.
8
Rapid hardening Cement is Costly.
There is a good speed of construction as the
cement sets rapidly.
It is a very durable cement which matches the
fast pace of construction and budgets required to
make projects operational.

2. PPC (Portland Pozzolana Cement)
The Portland Pozzolana Cement is a kind of
Blended Cement which is produced by either inter
grinding of OPC clinker along with gypsum and
pozzolanic materials in certain proportions or
grinding the OPC clinker, gypsum and Pozzolanic
materials separately and thoroughly blending them
in certain proportions.
10
Advantages and Uses
Higher durability of concrete structure due to
less permeability of water.
More resistance towards the attack of alkalies,
sulphates, chlorides, chemicals.
Better work ability.
Low heat of hydration.
11
Due to high fineness, PPC has better cohesion
with aggregates and makes more dense concreteness.
Comparative lower Water-Cement ratio provides an
added advantage for the further increase of
compressive strength of the concrete.
Better surface finish.

3. White Cement
White cement is a hydraulic binder whose physical
characteristics correspond to those of Portland
grey cement.
It is distinguished by its pure white color. This
whiteness is the result of nature, as well as the
rigorous selection of raw materials used in
manufacturing and a technologically advanced
production process.
13
Uses
Thermal properties of concrete based materials
can be far superior to other competitive
materials.
Reflectivity of light for use in flooring
applications in malls, schools, airports and
other large buildings, which reduces the
requirement excessive lighting which in turn
reduces energy costs.
White cement can be pigmented to achieve various
colors without the need for paint or stains thus
eliminating VOCs.
14
Reduction of the heat island effect by using
white based mix designs for the manufacture of
rooftop pavers, light colored pavers in
driveways, walkways, patios and around pools.
When concrete products reach the end of their
long useful life they can be recycled and used in
the manufacture of other products.

4. Portland Slag Cement (PSC)
Portland Slag Cement (PSC) is manufactured by
either inter-grinding in the Portland cement clink
er, Gypsum Granulated Slag or blending the
Ground Granulated Blast Furnace Slag (GGBS) with
Ordinary Portland Cement by means of mechanical
blenders.
16
Advantages and Uses
Reduced plastic shrinkage cracks.
Smooth surface finish.
Increased resistance to chlorides, sulphates,
carbon dioxide and such other harmful salts.
Reduced heat of hydration and thermal cracks.
17
Improved workability and cohesiveness of the mix.
Higher ultimate compressive and flexural strength.
Higher impermeability.
Increased resistance to Alkali silica reaction.
Durable and Sustainable Construction.
18
5. Ordinary Portland Cement (OPC)
Ordinary Portland Cement (OPC) is the most
common cement used in general concrete
construction when there is no exposure to
sulphates in the soil or groundwater.
19
Advantages and Uses
Produces highly durable and sound concrete due to
very low percentage of alkalis, chlorides,
magnesia and free lime in its composition.
Almost negligible chloride content results in
restraining corrosion of concrete structure in
hostile environments.
Significant saving in cement consumption while
making concrete of grades M15, M20, M25, M35 and
pre-cast segments due to high strength.
