Task 1 Cambridge 6 - Brick Manufacturing

You should spend about 20 minute on this task.

The diagram illustrated the process that is used to manufacture bricks for the building industry.

Summarise the information by selecting and reporting the main features , and make comparisons where relevant.

Write at least 150 words.

MODEL ESSAY:

The diagram is outlining the process of manufacturing bricks by the building industry. Overall, there are seven stages in this process, starting from the digging of clay and ending with delivery.

At the beginning of the process, clay is dug from the ground by a huge digger. It is then put through a metal grid before being passed on a roller where it is mixed with sand and water.  After that, the clay is either passed through a wire cutter, or put in a mould to shape the bricks.

In the next stage, the shaped bricks are then placed in a drying oven for one or two days. Thereafter, they are then heated in a kiln at a moderate temperature between (200 and 900 degrees Celsius). The bricks will then be moved to the next kiln with a higher temperature ranging between (870 degrees Celsius to 1300 degrees Celsius).

At the fifth stage of the process, the bricks will be stored in a cooling chamber for two to three days. Lastly, they will be packaged and sent for delivery by a truck.

Fun Facts!

A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote rectangular units made of clay-bearing soil, sand, and lime, or concrete materials. Bricks can be joined together using mortar, adhesives or by interlocking them.Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are fired and non-fired bricks.

Block is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate.

Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 4000 BC. Air-dried bricks, also known as mudbricks, have a history older than fired bricks, and have an additional ingredient of a mechanical binder such as straw.

Bricks are laid in courses and numerous patterns known as bonds, collectively known as brickwork, and may be laid in various kinds of mortar to hold the bricks together to make a durable structure.
