PRESENTATION ON BRICKS

2. Introduction
 A brick is an artificial kind
of stone made of clay
whose chief characteristics
are plasticity when wet and
stone like hardness after
being heated to high
temperature.

3. Standard Size of Brick
According to PWD
9.5”x4.5”x2.75”
After using mortar
10”x5”x3”

4. Constituents of Brick

5. Silica
 Good quality bricks contain 50-
60% silica.
 Silica prevents raw bricks from
cracking, shrinking and
warping.

6. Alumina
 Alumina is the main
constituent of clay.
 It acts as a cementing
material in raw brick.

7. Lime
 Lime reduces shrinkage
of bricks during drying.
 Bricks should contain a
little amount of finely
powdered lime.

8. Iron Oxide
 Iron Oxide acts a flux like lime,
thus helps silica to fuse at low
temperature.
 Iron also increases the
durability and impermeability
of the bricks.

9. Magnesia
 Magnesium decreases
shrinkage and gives a yellow
tint to the bricks.
 An excess amount of it causes
bricks to decay.

10. Harmful constituents of Brick clay
1) LIME
2) IRON PYRITES
3) ALKALIS
4) PEBBLES
5) VEGETATION AND ORGANIC
MATTER

13. Characteristics of Good Bricks
A. Bricks should be uniform in color, size and shape.
B. They should be sound and compact.
C. They should be free from cracks and other flaws such as
air bubbles, stone nodules etc.

14. Characteristics of Good Bricks(continue…)
D. Bricks should not absorb more than 1⁄5 of their own
weight of water when immersed in water for 24 hours.
E. The compressive strength of bricks should be in range of
2000 to 5000 psi.
F. Bricks should neither overburnt nor under-brunt.

15. Field Test of Bricks
 Take a brick and try to make mark on the surface by nail.
If we can make it, then it is not a good brick.
 Take a Brick and strike it with a hammer. If it gives
metallic sound, then it is a good brick; if not ,it is bad
one.

16. Field Test of Bricks(continue…)
Take two bricks and form a “T”
shape and drop from a height of 6
ft on a more or less solid surface.
If they break, they are not good
bricks. If they remain
unbroken ,they are good bricks.

17. Types of bonds in Brick works

18. Uses of Bricks
 Construction of walls of any size.
 Construction of floors.
 Construction of arches and cornices.
 Construction of brick retaining wall.

19. Uses of Bricks(continue…)
 Making Khoa (Broken bricks of required size) to use as an
aggregate in concrete
 Manufacture of shurki (powdered bricks) to be used in
lime plaster and lime concrete
