▶ Your Answer :
The two diagrams
represent Cement Production and Concrete Production respectively. These
diagrams are closely relevant, because cement is used to make concrete.
The cement production
diagram shows how to make cement with materials. First, limestone and clay are
changed to powder after passing through the crusher. Second, the powder is
mixed in the mixer, and then the mixed powder is heated by the rotating heater. Finally, cement is produced after the grinding stage and packed into bag.
On the contrary
to the cement production which has many lots of stages, process of making concrete
is much less complicated than cement-making. Looking at the process, gravel, sand cement and water (50%, 25%, 15% and 10% respectively) are put into a and these things are mixed by rotating clockwise. As a result, the produced Concrete is used
for building purpose.
Overall, concrete
is made by two production processes, and this concrete is used as one of the
ingredients for building purposes.
