The diagram below shows the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.

The given diagrams illustrate the schematic process and tools needed to produce

cement

, and concrete production for building purposes that use

cement

as one of its

materials

.

Overall

, there are five stages to make

cement

, starting from the crushing of two raw

materials

and ending with packing the

cement

,

while

there is only one stage to make concrete.

Firstly

,

cement

production starts by crushing limestone and clay in a crusher, which results in a powder that goes through the next machine, the mixer. After the mixing,

the next step is

putting the powder into a rotating heater, with heat coming from the fire. The half-ready powder

then

undergoes the

last

process, grinding, in a grinder to make it more refined and have an even size .

Lastly

, the finished

cement

is packed into bags.

Next,

the concrete is produced using

cement

which makes up 15% of its whole material proportion. It is mixed with 10% of water, 25% of sand, and 50% of gravel as the most dominant . All

materials

are put into a big machine called a concrete mixer that works continuously until all

materials

are evenly mixed and ready for building purposes.
