Diagram task 1

These diagrams illustrate the process of making cement first, followed by a visual explanation of concrete’s production. While cement is made through a sequence of much more passages, concrecte’s production seems to be easier as it requires less features.

First of all, limestone and clay are the materials used in cement production; these need to be crushed, and once a powder is obtained and mixed, it goes into a rotating heater. Subsequentially to this, the heated powder is smashed thanks to a grinder and cement is obtained. This is usually conserved in bags.

Finally, concrete production can start. However, the process requires four materials instead of the two used in cement production. The suggested proportions are a half of gravel, a quarter of sand and the last quarter divided between 15% of cement and 10% of water. These have to be poured in a rotating concrete mixer.

Check and grade please

Cement Making

by poonkodi

The diagram illustrates the procedure in which cement are made, and how cement used for manufacture of concrete for building purposes.

Overall, production of cement includes five step process and only two stages for processing of concrete.

To begin with, for the cement production limestone and clay are crushed with a crusher and product acquired as a powder form. This powder is mixed with a mixer then, with help of rotating heater heat is applied in the bottom. At last, by using grinder the final product is obtained as fine particles. This particle is called cement and at the end packaged in the bags.

Next, cement is converted into concrete by adding different materials. Cement is mixed with water, sand, and gravel in the proportion of 10%,25%,50% respectively. This mixture is then put into a concrete mixer, where it becomes final concrete which can be used for building purposes.
