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.
The diagrams illustrate how cement is produced and also an example of cement utilisation produced to make concrete to use in a form of construction.
To begin with, cement is produced by combining raw materials like limestone, clay, which are processed in a tool called crusher. Those all items are mixed together to create a perfect blend. The blend, furthermore, goes into to a rotating heater. As it is in the rotating heater tube, heat is introduced from the end of the tube before the blend is actually dropped onto grinder. Then, after all the systemic process, the mixture turns into some cement which is then packed into bags.
Meanwhile, to create concrete, the main components of construction systems are gravel, cement, water, sand and a concrete mixer to blend all the materials. Gravel or small stone is the major and biggest component needed and accounts for 50% among all materials. There are, however, some other materials like the sand which is mainly used and comes in the second place and is accounted halved from gravel, followed by cement and water. The cement accounts for 15% compared to among all materials used to construct a new real construction. All the material is mixed together by a concrete mixer.
Overall, the steps of making cement are more complicated and require advanced machinery while concrete production requires mixing required components in the right proportion in a simpler machine. While heat is required to produce cement, no heat penetration during the combination period of making concrete is required.

这些图表说明了水泥是如何生产的，也是水泥利用的一个例子，水泥利用生产的目的是使混凝土以一种建筑形式使用。
首先，水泥是由石灰石、粘土等原材料混合而成，这些原材料在一种称为破碎机的工具中加工而成。所有的物品混合在一起，形成完美的混合。此外，混合物进入旋转加热器。由于是在旋转加热管中，在混合物实际落到研磨机上之前，热量从管端引入。然后，经过所有的系统过程，混合物变成一些水泥，然后包装成袋。
同时，为了创造混凝土，施工系统的主要组成部分是砾石、水泥、水、沙和混凝土搅拌机来混合所有的材料。砾石或小石子是所需的主要和最大成分，占所有材料的50%。然而，还有一些其他材料，如砂，主要用于第二位，从砾石中减半，然后是水泥和水。与所有用于建造新的实际建筑的材料相比，水泥占15%。所有材料由混凝土搅拌机混合在一起。
总的来说，制造水泥的步骤更为复杂，需要先进的机械，而混凝土生产需要在更简单的机械中按正确的比例混合所需的组分。虽然生产水泥需要热量，但在制备混凝土的组合期间不需要热量渗透。
