You should spend about 20 minutes on this task. 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 provided illustrate the processes of preparing

cement

and how concrete is made from it,

along with

the various steps and equipments that are involved in their production.

Then

this

cement

which is later packed into bags.

Then

to make the concrete, 15% of

cement

is added into a big concrete mixer, to which 10% of water, 25% of sand and 50% of gravel is added.
