Concrete, Cement, Raw Material of Cement, Types, Water, Aggregates, Sand, Mix...Naqeeb Khan Niazi
Concrete is an engineering material that simulates the properties of rock and is a combination of particles closely bound together. It is simply a blend of aggregates, normally natural sand and gravel or crushed rock.
Cement is a dry powdery substance made by calcining lime and clay, mixed with water to form mortar or mixed with sand, gravel and water to make concrete. It is a binder material. Once hardened, cement delivers sufficient strength to erect large industrial structures
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.
Sand a loose granular material that results from the disintegration of rocks, consists of particles smaller than gravel but coarser than silt, and is used in mortar, glass, abrasives, and foundry molds. : soil containing 85 percent or more of sand and a maximum of 10 percent of clay.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

This presentation is about the working procedure of Shahjalal Fertilizer Company Limited (SFCL). A Govt. owned Company of Bangladesh Chemical Industries Corporation under Ministry of Industries.
2. • A cement is a binder, a substance used in construction
that sets, hardens and adheres to other materials,
binding them together. Cement is seldom used solely, but
is used to bind sand and gravel (aggregate) together.
Cement is used with fine aggregate to produce mortar for
masonry, or with sand and gravel aggregates to
produce concrete.
• There are different types of cement…..
4. • Acid-resistance aggregates such as quartz,
quartzites, etc.
• Additive such as sodium fluosilicate Na2SiF6
• Aqueous solution of sodium silicate or
soluble glass.
• The addition of additive sodium flousilicate
accelerates the hardening process of
soluble glass and it also increases the
resistance of cement to acid and water.
• The binding material of acid-resistance
cement is soluble glass which is a water
solution of sodium silicate, Na2O.nSiO2 or
potassium silicate, K2O.nSiO2, where n is
the glass modulus.
• The acid-resistance cement is used for acid-
resistance and heat resistance coatings of
installations of chemical industry. It is not
water-resistant and it fails when attacked by
water or weak acids. By adding 0.5 percent
of linseed oil or 2 percent of ceresit, its
resistance to the water is increased and it is
then known as the acid and water resistant
cement.
Acid-resistant
cement is composed
of the following:
5. • For this cement type, the slag as
obtained from blast furnace is
used. The slag is a waste product
in the manufacturing process of
pig-iron and it contains the basic
elements of cement, namely
alumina, lime and silica. The
clinkers of cement are ground with
about 60 to 65 percent of slag.
• The properties of this cement are
more or less the same as those of
ordinary cement. Its strength in
early days is less and hence it
requires longer curing period. It
proves to be economical as slag,
which is a waste product, is used in
its manufacture. This cement is
durable, but not suitable for use in
dry arid zones.
Blast furnace cement
is composed of the
following:
6. • The cement of desired colour may
be obtained by intimately mixing
mineral pigments with ordinary
cement. The amount of colouring
material may vary from 5 to 10
percent. If this percentage exceeds
10 percent, the strength of cement
is affected.
• The chromium oxide gives green
colour. The cobalt imparts blue
colour. The iron oxide in different
proportions gives brown, red or
yellow colour. The manganese
dioxide is used to produce black or
brown coloured cement.
• These types of coloured cement
are widely used for finishing of
floors, external surfaces, artificial
marble, window sill slabs, textured
panel faces, stair treads, etc.
Coloured cement is
composed of the
following:
7. • This type of cement is
produced by adding an
expanding medium like
sulpho-aluminate and a
stabilizing agent to the
ordinary cement. Hence
this cement expands
whereas other cements
shrink.
• The expanding cement is
used for construction of
water retaining structures
and also for repairing the
damaged concrete
Expanding cement is
composed of the
following:
8. • This cement is produced by
grinding clinkers formed by
calcining bauxite and lime.
It is specified that total
alumina content should not
be less than 32 percent and
the ratio by weight of
alumina to lime should be
between 0.85 to 1.30.
High Alumina cement
is composed of the
following:
9. • This type of cement
contains admixtures which
decreases the wetting
ability of cement grains.
The usual hydrophobic
admixtures are acidol,
napthenesoap, oxidized
petrolatum, etc. Use of
hydrophobic cement
considerably increases the
water resistance of an
concrete.
Hydrophobic cement
is composed of the
following:
10. • The considerable heat is
produced during the setting
of cement. In order to reduce
the amount of heat, this type
of cement is used. It contains
lower percentage of
tricalcium aluminate C3A of
about 5% and higher
percentage of dicalcium
silicate C2S of about 46%.
• This cement possesses less
compressive strength. The
initial setting time is about
one hour and final setting
time is about 10 hours. It is
mainly used for mass
concrete work.
Low heat cement is
composed of the
following:
11. • Pozzolana is a volcanic
powder. It is found in Italy
near Vesuvius. This type of
cement is used to prepare
mass concrete of lean mix
and for marine structures. It
is also used in sewage
works ad for laying
concrete under water.
Pozzolana cement is
composed of the
following:
12. • This cement is produced by adding
a small percentage of aluminium
sulphate and by finely grinding the
cement. The percentage of gypsum
or retarder for setting action is also
greatly reduced. The addition of
aluminium sulphate and fineness of
grinding are responsible for
accelerating the setting action of
cement. The setting action of
cement starts within five minutes
after addition of water and it
becomes hard like stone in less
than 30 minutes or so.
• The extreme care is to be taken
when this cement is used as mixing
and placing of concrete are to be
completed in a very short period.
This type of cement is used to lay
concrete under static water or
running water.
Quick setting cement
is composed of the
following:
13. • The initial and final setting
times of this cement are
same as those of ordinary
cement. But it attains high
strength in early days. It
contains high percentage of
tricalcium silicate C3S to the
extent of about 56%.
Rapid hardening
cement is composed
of the following:
14. • In this cement, the
percentage of tricalcium
aluminate C3A is kept
below 5 percent and it
results in the increase in
resisting power against
sulphates.
• This type of cement is used
for structures which are
likely to be damaged by
severe alkaline conditions
such as canal linings,
culverts, siphons, etc.
Sulphate resisting
cement is composed
of the following:
15. • This just a variety of
ordinary cement and is
prepared from such raw
materials which are
practically free from
colouring oxides of iron,
manganese or chromium.
For burning of this cement,
the oil fuel is used instead
of coal. It is white in colour
and is used for floor finish,
plaster work, ornament
work, etc.
White cement is
composed of the
following:
16. • It is produced by adding
indigenous air entraining
agents such as resins,
glues, sodium salts of
Sulphates etc during the
grinding of clinker. This type
of cement is specially
suited to improve the
workability with smaller
water cement ratio and to
improve frost resistance of
concrete.
Air entraining cement
is composed of the
following:
