TYPES OF BRICKSTYPES OF BRICKS
Three types of bricks:Three types of bricks:
Clay bricks:Clay bricks:
1) Common bricks1) Common bricks
2) Facing bricks2) Facing bricks
3) Engineering bricks3) Engineering bricks
4) Fire bricks4) Fire bricks
Silica bricks/ sand-lime bricks (calcium Silica bricks/ sand-lime bricks (calcium silicate)silicate)
Cement bricksCement bricks
Types of Bricks Uses of Bricks in Civil Engineering
A) Common bricks
-have a dull texture and
poor colour
- Used for internal and rear walls that need to be plastered
B) Facing bricks
-Pleasant looking texture
-Capable of withstanding
the effects of weather
-Used for constructions that do not need to be plastered because of pleasant appearance
Types of Bricks Uses of Bricks in Civil Engineering
C) Engineering bricks
-Very hard, dense and do not easily absorb water
-Mainly used for walls carrying exceptionally heavy loads. Examples : retaining walls , foundation
D) Fire bricks
-Able to resist high
temperature
-Mainly used for constructions that need to resist high temperatures like kiln or boiler
Types of Bricks Uses of Bricks in Civil Engineering
2. Sand-lime bricks/ silica brick (Calcium silicate)
-Materials
hydrated lime
Clean sand
ratio of 1:8
-As an alternative for replacing ‘Common Clay Bricks’
-for internal and rear walls

Advantages and Advantages and disadvantages disadvantages
of Bricksof Bricks
Advantages Disadvantages
1. Easy to be used in building walls
2. Easily managed/ handled
3. Facing bricks can be made as decoration without plastering
4. Can be used as pier
5. Acid or alkaline resistance
1. Plastering work requires skilled workers
2. Low tensile-strength
