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 Summarize the information by selecting and reporting the main features and make comparisons where relevan

The first chart illustrates cement production with four steps and the packing process while the second one how concrete production is made.

To begin with, the first chart shows how cement is made, initially, the limestone and clay are become powder by crusher and mixed. After that, they are heated in the rotating heater and granulated with a grinder. Following this process, cement is obtained and packaged into bags.

To continue with, when it comes to the second chard there are four ingredients are used for concrete production. First of all, those ingredients are mixed in certain proportions in a concrete mixer. Those ingredients are cement, water, sand, and gravel, which are consist of small stones, they have 15, 10, 25, and 50 percentages, respectively. Finally, the mixture is ready for building construction.
