The diagrams below show the stages and equipment used in the cement making process and how cement is used to produce concrete for building purposes Summaries the information by selecting and reporting the main features and make comparisons where relevant

The two diagrams describe the processes in which cement and concrete are produced.

It is clear the the cement production includes five steps, beginning with crushing limestone and clay and ending with packaging, while the production of concrete has only two steps.

Looking at the first process, initially limestone and clay are put through a crusher that is responsible for transforming them into powder. Secondly, the powder is then poured into a mixer where the components are blended. After that, the resulting product is moved through a rotating heater at a high temperature, followed by the grinding process to create cement which is finally packed into bags for storage and delivery.

Regarding the second process, cement and other materials including gravel, sand and water are prepared at appropriate proportions, 15%, 50%, 25% and 10% respectively. Following that, they are all poured into a mixer which rotates to form concrete for building purposes.
