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 first diagram illstrustrates the process of producing

cement

and

ingredients

required

while

the second diagram highlights how to turn

cement

into concrete. The first process of producing

cement

is to add limestone and clay into the crusher which turned them into powder form. After that, limestone and clay powder go through a mixer and

then

drop to a rotating heater where it turns and heat up the mixture. The heated up

cement

mixture will

then

go through a grinder which finished

cement

is ready to be packed in bags. In the second diagram, it shows that concrete is created by a combination of four

ingredients

, which includes 15% od

cement

, 10% of water, 25% of sand and 50% of gravel. All of these

ingredients

are added into the concrete mixer and turns into concrete.

Overall

,

cement

is produced by limestone and clay, which go through the process of crushing, mixing, heating and grinding. After

cement

is made, it is one of the four main

ingredients

to be added to create concreate.
