The diagrams show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.
Writing Task 1
The diagrams reveal the information regarding to some steps and tools that are used to produce cement and concrete for building purposes. Overall, it is noticable that, cement production needs more equipment and complex stages than concrete production does. In addition, concrete cannot be produced before cement-making process is finished.
To begin with, there are two main materials which should be prepared for producing cement, that are limestone and clay. First step, these materials are crushed by crusher untill the material sizes powder. Secondly, after being mixed, it will be rotated with certain temperature to heat it in rotating heater. Thirdly, the material needs to be processed in grinder to produce cement. Fourthly, cement can be packed by using large bags.
After cement being produced, concrete-making process can be started. To create it needs 15% of cement, 25% of sand, 10% of water, and a half of stone with small size. The first step is that pour these materials into concrete mixer. After being poured, mixed together by rotating the tool. Finally, concrete can be already used. (177 words)
