- A brick is a block of
ceramic material used in masonry construction and sized to be layed with
one hand using mortar. Bricks may be made from clay, shale, soft slate,
calcium silicate, concrete, or shaped from quarried stone. Clay is the
most common material, with modern clay bricks formed in one of three
processes - soft mud, dry press, or wire cut.
- The soft mud method is
the most common, as it is the most economical. It starts with the raw
clay preferably in a mix with 25-30% sand to reduce shrinkage. The clay
is first ground and mixed with water to the desired consistency for
forming in a mould. The clay is pressed into steel moulds with a
hydraulic press. The shaped clay is then fired ("burned") at 900-1000°C
to achieve strength.
- In Pakistan and India,
brick making is still typically a manual process. The most common type
of brick kiln in use there are Bull's Trench Kiln (BTK), based on a
design developed by British engineer W. Bull in the late 1800s.
- The fired colour of
bricks is significantly influenced by the chemical and mineral content
of raw materials, the firing temperature and the atmosphere in the kiln.
For example pink coloured bricks are the result of a high iron content,
white or yellow bricks have a higher lime content. Most bricks burn to
various red hues, if the temperature is increased the colour moves
through dark red, purple and then to brown or grey at around 1300°C.
Calcium silicate bricks have a wider range of shades and colours.

- A fully indigenous
brick making machine has been developed which brings in semi
mechanisation within the reach of a common brick manufacturer. Within
the reach of a common brick manufacturer. With the use of this extrusion
machine, a small scale unit can produce 2,500 wire cut bricks of 225*
112.5* 75 mm size in an hr. It can also produce other forms of clay
units useful for flooring and roofing purpose. An automatic reel type
cutter and a high draught brick kiln is used in conjunction with this
machine.
- Redmud improves the
quality of bricks made from inferior soils deficient in clay content.
Red mud compositions give bricks of pale brown, orange or golden
yellowcolour depending upon composition of raw material and firing
temperature. They have therefore good architectural value as facing
bricks. The presence of 4-5 % of alkali in redmud provides a fluxing
action resulting into good plasticity and a better bond in the bricks.
These can be used for all types of construction.
- Although the basic
principles of manufacture are fairly uniform, individual manufacturing
plants tailor their production to fit their particular raw materials and
operation. Essentially, brick are produced by mixing ground clay with
water, forming the clay into the desired shape, and drying and firing.
In ancient times, all molding was performed by hand. The manufacturing
process has six general phases: 1) mining and storage of raw materials,
2) preparing raw materials, 3) forming the brick, 4) drying, 5) firing
and cooling and 6) de-hacking and storing finished products.
- The demand for bricks
is expected to be about 100 billion per year by the turn of the century.
Even if only 50% of the estimated demand of 100 billion bricks per year,
is met from fly ash for productive use saving alternate resources, and
reducing environmental hazard to that extent. In addition, it would save
thousands of hectares of land from being used as ponding area.
