Band 6+: The diagram below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagrams illustrate the five main steps of cement production, while the second diagram shows a process of concrete production.

Overall, there are four main steps in the cement production starts from crushing ingredients to packed into bags, which are all done by using an automatic machine. In addition, the cement produced in added along with other ingredients to be mixed for the production of concrete in a single step.

The first diagram illustrates four steps of producing cement. First, paste Limestone and clay into a machine. Second, the crusher inside will crush them into powder. Then, when the power go into a Mixer, they are heated by the Rotating heater. Lastly, they go into the grinder and become cement then packed into bags.

In addition, the second diagram demonstrates the single step of concrete production. The process is done by adding four ingredients : gravel ,which is the most significant, 50%; sand, 25%; cement, 15%; and water, 10% to concrete mixer, finishing to be concrete.
