The diagrams illustrate the phases and apparatus to make cement and how
cement is utilised in the production of concrete for construction.

The production of cement involves a 5 stage, linear process that begins with
the mixing of raw materials and culminates in the packaging of new cement.
Making concrete is a simpler process that involves mixing four ingredients in a
concrete mixer.
Limestone and clay are crushed and the resulting powder is then mixed before
being passed through a rotating heater. Once heated this mixture travels over a
conveyor belt and is ground through a grinder. Now that the cement has been
produced, it is packaged and transported to a building site where it can be used
to make concrete.
Concrete is made up of half gravel, quarter sand, 10% water and 15% cement.
All of these are added together in a cylindrical drum and rotated until concrete
is yielded.
