选项
答案
There are two diagrams which illustrate the cement producing process and how concrete is made using cement.
The production of cement consists of four main stages. To start with, limestone and clay are poured into a crusher where they are ground into powder. The resulting powder is then put through a mixer and then into a clockwise rotating heater. After heating, the powder can be ground into cement by grinder. Finally, the cement is packed up in bags.
Compared with the making process of cement, the production of concrete is relatively easy. 15% of cement, 10% of water, 25% of sand and 50% of gravel, which means small stones, are poured into a concrete mixer; then the mixer starts to rotate clockwise constantly to make sure these four materials can be mixed evenly before they are used for building purposes.
Overall, these two diagrams together present how natural materials are transformed into cement, men furthermore to become concrete.
