Topic: The diagram below shows the process by which bricks are manufactured for the building industry. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

Answer 1

The diagram explains how bricks are made for making different kinds of buildings or structures. The first phase involves looking for raw materials, usually clay, and dug out of the earth. Next, the clay is brought into the factory and is passed through a wire mesh. It breaks up the big chunks of clay into smaller ones. It now becomes easier to give the desired shape. Additional products are added to the tiny lumps of clay which mainly involves sand and water. After adding sand and water, the final mixture can be used for two different purposes. Firstly, it can be used for making bricks involving cutting the semi-solid mix with a wire cutter. Secondly, the same mixture is also used for making molds.

The next step is significant since it helps retain the shape given to the bricks or molds in the previous actions. The semi-solid bricks and molds are dried in a drying oven for 24 to 48 hours. This prepares them for the next step, which involves intense heating for many hours. After the drying process, the bricks and molds are placed in a brick kiln where they are subjected to a moderate temperature ranging between 200 degrees Celsius to 900 degrees Celsius. However, the heating process doesn't end here, and now they are subjected to intense temperatures ranging between 870 degrees Celsius and 1300 degrees Celsius. Finally, the heating process comes to an end with a cooling period of 48 to 72 hours. Now, they are hard and ready for packaging.

Upon the end of the cooling period, the bricks are packed in a square formation, which prevents them from getting damaged, and at the end, trucks are used for delivering them to their destination.

Answer 2

The manufacturing of bricks is a simple yet intense heating cooling and finally packaging them for the building industry. The process starts when a digger digs big chunks of clay from a mining site. These chunks are the raw materials with what bricks are primarily made. Next, after digging, they are brought into the factory, where they are passed through a wire-mesh. This helps to divide them into powdered granules, subsequently making them suitable for mixing and adding other similar raw materials. These other raw materials include sand and water. After thorough mixing and turning them into a semi-solid mixture, they are shaped according to different requirements. There are different demands, but the primary demand is bricked. Some of the clay is also shaped in the form of molds which make up the additional demands. This completed the first line of production.

The following production line includes modifying the bricks and taking them from the semi-solid stage to a tough form. Both bricks and molds are placed in a drying room where they are kept for as long as 24 to 48 hours to thoroughly dry them and bring out any instances of moisture from them. This step also prepares the bricks and molds for the high temperatures in the heating oven. After completely dried, the bricks and molds are taken from the drying chamber to the heating ovens. Here, the heating process is divided into two phases. The first phase includes moderate heating, and a very high-temperature environment follows it. The chamber where this entire process takes place is called the kiln. In this kiln, the bricks and molds are subjected to a temperature of 200 degrees Celsius to 900 degrees Celsius for the first phase. After this process, the kiln's temperature is gradually increased until it reaches the temperature range of 870 degrees Celsius to 1300 degrees Celsius. This makes them permanently hard, but the entire process is not completed until they are given the appropriate time for cooling. This cooling session goes on for 48 to 72 hours.

Finally, the bricks are packaged and delivered to the desired destination for use.

Answer 3

The above diagram explains the multiple steps in manufacturing bricks for making houses, offices, and other permanent infrastructures like stations and airports. Bricks are hard entities, but their journey starts from a raw material known as clay, usually dug out of the earth. Initially, they are dug out in chunks and are not suitable for making bricks. Subsequently, when they are brought into the factory for processing, they are broken down into small manageable bits using a wire mesh, and the small granules fall onto a conveyor belt. However, clay alone cannot make hard bricks. The factory adds sand and water to the clay, and a mixture is formed. This mixture takes a semi-solid form and is usually cut into and shaped into bricks using a wire cutter. Some of the mixtures are also reserved for making squared hollow molds.

These wet but semi-solid products are now placed in a drying oven for an extended period of 24 to 48 hours. Only after the drying process is completed, the dried bricks and molds are placed in a Kiln. A Kiln is a particular type of heating oven where high temperatures are achieved and used to harden the bricks and molds permanently. So, in this step, the dried products are placed in the kiln and are subjected to two phased temperatures. The first phase involves a temperature between 200-900 degrees Celsius, while the second phase involves a higher range of 870-1300 degrees Celsius. The first phase is the moderate phase, and the second phase is the high phase. The next step that follows the super-heated bricks and molds are placed in a cooling chamber for heat dissipation. The cooling usually takes a minimum of 48 hours and can sometimes go up to 72 hours.

After the cooling is completed, the bricks are ready for packaging. Finally, the packaged are taken out of the factory in trucks to their final destination.
