The diagram below shows 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 v.5

The diagrams illustrate the way in which cement is made and how it is used create a concrete production. Overall, this man-made process consists of five stages to make cement, beginning with putting limestone and clay in the crusher and ending up with packaging cement into bags. This cement, with other elements, is ready to be mixed to begin a concrete production. [62 WORDS] First of all, limestone and clay are put into crusher together, where they are reduced as powder. After that, the powder is placed into mixer automatically, and next it passes into rotating heater, where is given heat from outside. In the subsequent stage, it is pressed by a grinder, and following that the result is cement. In the last passage the cement is divided into several bags. [129 WORDS] Finally, the cement, about 15% with the addition of other elements, in particular percentage, like a quarter of sand, an half of gravel, and the rest of water, is ready to mix to achieve the concrete production.
