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 diagrams illustrate the process of

cement

production

along with

how to produce concrete from

cement

.

Overall

, there are 5 main stages commencing with the crushed limestone and clay being mixed prior to heating, grinding, and ultimately packaging.

Additionally

, the concrete will be manufactured by mixing key materials

such

as

cement

, water, sand, and gravel.

Initially

, the limestone and clay are crushed and converted into powder.

Then

the powder goes through the mixer and rotating heater in order to be heated for a

while

.

After

this

stage is complete, the powder undergoes the grinding stage which is continuously ground into

cement

and is ready for packaging. Turning to concrete production, before not only the sand which is made up 25% but

also

the gravel ( 50% ) is put into the concrete mixer, the

cement

,

as well as

the water, accounted for 15% and 10% poured into the mixer, respectively.

Finally

, through ample blending, concrete is made out.
