The diagrams illustrate the way in which cement is made and how it is then used
in the process of making concrete. Overall, limestone and clay pass through four
stages betore being bagged ready for use as cement which then accounts for 15% of
the tour materials used to produce concrete. While the process of making cement
uses a number of tools, the production of concrete requires only a concrete mixer.
In the first stage of making cement, limestone and clay are crushed together to
form a powder. This powder is then combined in a mixer betore passing into a
rotating heater which has constant heat applied at one end of the tube. The
resulting mixture is ground in order to produce cement. The final product is
afterwards put into bags ready to be used.
Regarding the second diagram, concrete consists of mainly gravel, which is small
stones, and this makes up 50% of the ingredients. The other materials used are
sand (25%), cement (15%) and water (10%). These are all poured into a concrete
mixer which continually rotates to combine the materials and ultimately produces
concrete.
