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.

The first diagram shows that the data of process and equipment used in the cement making, while the second diagram represents how concrete is produced by using cement for building purposes.

In the beginning, materials such as limestone and clay are poured into crusher which makes a powder. This powder then passed through mixer, before this is processed through rotating heater, which requires heat to work. Further, the mixture goes into a grinder from which cement comes out. At the end of the process, cement is packed in bags.

Referring to the concrete production, the process comprises four elements namely cement with the percent of 15%, water with 10%, sand with 25% and gravel consisting of 50%. These four elements are introduced into a concrete mixer to make concrete.

Overall, it is clear that cement production is a part of concrete production as cement is used in the process of making concrete, however, more materials are used in the production of cement to obtain the final product.
