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

The diagrams illustrate the stages and equipment used in

cement

production

and concrete

production

. I will explain

this

production

process in the following paragraphs in detail.

Overall

, the manufacturing of

cement

consists of various tools

such

as a mixer, rotating heater, crusher and grinder

The powder

is mixed and heated,

from the heated powder. Those

cement

powders are packed in bags for future use. Next is concrete manufacturing , in concrete manufacture different materials are used to produce

cement

, including

cement

15%, 25% of sand ,50% of gravel which is small stones and 10% of water are put into the concrete mixer and

then

it

finally
