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. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The two pictures illustrates the

process

and equipment used in the

cement

-making

process

and how is it made

cement

with produce concrete for building purposes

Overall

,we can see two scheme which is used to various produce for receipt

cement

and concrete.First of all for production

cement

the

process

consist of 10 stages.Beginning with crushing limestone and clay and ending up with receiving bags of

cement

.

Secondly

to obtain concrete,certain materials are required

such

as:

cement

(15%),water(10%),sand(25%),gravel(50%) and concrete mixer.

Firstly

,limestone and clay are passed through crusher,resulting in a fine powder.Next

this

powder is mixering and heated .Rotating heater assists on

this

process

.With helping grinder we have

cement

which is put into bags and ready for use In the next stage for production concrete we put 15% of

cement

together with

10% of water and 25% of sand

following

this

we put with small stones 50% of gravel.Subsequentlymixering all produce we have concrete.
