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 relevant.

The following diagrams represent the steps and equipment utilized in the production of the cement and how it is used in manufacturing concrete for building purposes. Overall, the primary products in making the cement are limestone and clay, while the end product is cement. The raw materials of concrete manufacture are cement, sand, gravel, and water which produce concrete as a final product. In cement production, the limestone and clay are crushed in the crusher. Subsequently, the produced powder is mixed in the mixer, then it is pass through the rotating heater. After that, it is heated by the heat and it is grinded by the grinder. As a result, the cement that is made is filled inside the bags. In concrete manufacture, the 15% of the cement, 10% of the water, 25% of the sand and 50% of the graver are mixed inside the concrete mixer and finally the concrete is produced.
