Introduction
CEMENT COURSE
History
Cement was first invented by the Egyptians. Cement was
later reinvented by the Greeks who made their mortar out of
lime. Later, the Romans produced cement from pozzolana, an
ash found in all of the volcanic areas of Italy, by mixing the ash
with lime.
The Egyptiens discovered lime
and gypsum mortar but to build
Pyramids they used only stones.

3.  Raw Materials
There are two types of raw materials which are combined to make
cement:
1. Lime-containing materials, such as limestone.
2. Clay and clay-like materials, such as slag from blast furnaces,
bauxite, iron ore, silica, sand, etc.
It takes approximately 3,400 lbs*. of raw materials to make one
ton (2,000 lbs*.) of Portland cement.

 Defination
Cement is a fine powder which, when mixed with water,
forms a thick paste. When this paste is mixed with sand and
gravel and allowed to dry it is called concrete.

Process
The mixture of materials is finely ground in a raw mill. The
resultant raw mix is burned in a rotary kiln at temperatures
around 1450 degrees Celsius to form clinker. The clinker
nodules are then ground with about 3 - 5 % gypsum to produce
cement with a fineness typically of less than 90 micrometers.

The study of a cement plant starts with the search for raw
materials and the identification of their chemical and
physical characteristics,.The next stage is to select the
appropriate process for preparing the raw meal by evaluating
the raw materials needed to obtain the clinker-after that
cements, looking at each and every stage of manufacture
(quarry extraction, crushing, pre-homogenization, control and
homogenization system, burn process, etc.), Looking after
solutions to make easy the quality control.

A. Alite (C3S).
B. Belite(C2S).
C. Aluminate (C3A).
D. Ferrite low quantity (C4AF).

Gypsum added to the clinker during grinding not
only regulates the setting time but also modifies some
properties of the hardened paste such as the
mechanical strength, shrinkage, resistance to sulfate
attack and the heat of hydration.
All of these properties represent optimum values in
relation to the given dosages of gypsum (3.0 – 5.0 %)
