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

The diagram illustrates the steps involved in cement production and how cement is then used to manufacture concrete for construction.

Overall, two raw ingredients (limestone and clay) are processed in four stages before being packed. The cement is then mixed in specific proportions with three other materials to produce concrete.

The first stage of making cement involves crushing clay and limestone into a powder, which is then combined in a mixer. This powder is passed through the rotating heater before being ground into cement. The final product is put into bags ready for use.

To prepare concrete, the cement is added to a large machine known as a concrete mixer, along with three other ingredients. Gravel, or small stones, accounts for half of the mixture, while the remaining ingredients are sand (25%), cement (15%) and water (10%). The mixer rotates to combine these materials, ultimately producing concrete.
