The diagram below shows the stages and equipment used in the cement-making progress, 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 diagram illustrates the machinery and steps involved in the

production

of

cement

and the subsequent

process

of concrete

production

for construction. In terms of

cement

production

, the

process

begins with crushing two key raw

materials

, limestone and clay, into a fine powder using a crusher.

This

powder is

then

thoroughly mixed in a mixer.

Afterward

Afterwards

show examples

, it passes through a rotating heater, where it is exposed to heat, and is

further

ground by a grinder to produce the final

cement

.

This

cement

is

then

packaged in bags for storage and distribution. Moving on to concrete

production

,

cement

is combined with three additional

materials

: gravel (50%), sand (25%), and a smaller portion of water (10%). These

materials

are mixed together in a concrete mixer to form concrete, which is used in construction. In conclusion,

while

the

cement

-making

process

involves several specialized machines and steps, the concrete

production

process

is relatively simple, requiring only the combination of

materials

in a concrete mixer.

Cement

serves as the key ingredient in concrete

production

,

along with

gravel, sand, and water.
