A brick is a man-made building material used to make walls and make places to walk. Or it is a rectangular blocks of baked clay used for building walls, which are usually red or brown.
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. To know the manufacturing process of Bricks, Mohta Cement Pvt. Ltd. going to describe how bricks produce and which type of qualities should be in bricks.
How Bricks are manufactured?
Manufacturing of bricks consists of the following 4 operations or steps.
- Preparation of brick clay or brick earth
- Moulding of bricks
- Air drying of bricks
- Burning of bricks
1. Preparation of Brick Material
Soil has to be excavated first and then laid out on a leveled ground. This soil has to be separated from impurities like stones, gravel, vegetation, etc. It is then exposed outside for a few months. This is known as weathering. After weathering, the soil is mixed with other components to make it durable for brick use. The clumps in this mixture are then broken up, kneaded and watered. This is called tempering.
2. Brick Moulding
Brick Moulding is done in two ways:
- Hand Moulding
- Machine Moulding
In hand moulding, the tempered soil which is now known as clay is etched into a mould such that it fits every nook and corner. Any extra clay is removed using a wooden frame or wire. After completion, the clay is taken out of the mould.
Machine moulding can be done in two ways. Either using a Plastic Clay machine or a Dry Clay machine.
With a plastic clay machine, the clay is etched into rectangular openings that are equal to the length and breadth of a brick and then cut into the thickness of a regular sized brick using wires or a frame.
With dry clay machines, the clay is reduced to a powder like form which is filled in the mould and subjected to high pressure which causes it to form into hard bricks.
3. Drying of Bricks
Bricks are usually laid out for 1-2 weeks for drying. It is important to remove maximum amount of moisture to save fuel and energy before burning the bricks(next stage).They are dried out till only 5–7% of moisture content is left.
Damp bricks are also more likely to crack if they are subjected to heat directly.
4. Brick Burning
This can be done in two ways: Kiln burning and Clamp burning.
A kiln is like an oven that produces high temperatures suitable for hardening and drying materials. Moulded clay is placed in the kiln and slowly dried at extremely high temperatures. This process is done using continuous and intermittent kilns.
Clamp burning is a method where unbaked bricks are stacked in a pit along with fuel, firewood, coal, etc and sealed with clay. This is then fired in a slow process that takes a few days.
