The diagrams display the processes involved in producing cement and concrete. Cement is one of the ingredients needed to make concrete.

Cement is produced by crushing a mixture of limestone and clay into a powder, using a tool known as a crusher. This powder is mixed by a mixer, then rotated in a cylindrical heater. Heat is applied to the bottom of the rotating heater. The resulting mixture, which is lumpy, is then ground into a finer powder by a grinder. This is the finished product, which is then put into bags.

Making concrete is an altogether simpler process than making cement. However, both processes involve mixing ingredients by rotating them. Half of the concrete mixture is gravel, which simply comprises small stones. A quarter of the mixture is sand. These two ingredients are mixed with water, which makes up a tenth of the mixture, and cement, which makes up 15% of the total mixture. These ingredients are poured into a concrete mixer, which rotates to make concrete. Unlike cement production, this process does not involve heat.
