The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes

The two diagrams illustrate how

cement

is produced from natural raw materials and the process of concrete manufacture. In general, the

cement

production visual shows that

cement

is made of limestone and clay,

while

the concrete diagram depicts that concrete is made from

cement

, sand , gravel and water in certain quantities. To start with

cement

manufacture , in the first stage , limestone and clay are added in specific amount together into the crusher which grinds the two material to a powder , after that the powder is transferred to the mixer which after mixing deliver the mixture into the rotating heater where external heat is applied.

then

the mixture is moved by a conveyer belt into the grinder to grind the lumpy mixture to powder again , the

last

stage is the packaging of the

cement

in bags .Moving on to concrete production , the process simply starts with mixing the four raw materials in certain quantities that are ;

Cement

15% , Sand 25%, Gravel 50% and water 10% , these materials are added to the mixer to produce concrete.
