Brick work
BRICKS WORK
An assembling of bricks properly bounded together in mortar is
called brick work or brick masonry. It is a type of masonry, in
which the bricks are arranged in mortar in such a manner
as to form a homogeneous mass of the structure. In such a
structure, the point or other loads and stresses are dispersed and
distributed throughout the mass without tending to disintegrate the
structure.
The mortar that is used in bricks work may be may mortar, lime
mortar, or cement mortar, depending upon the class and strength of
work desired. Bricks work are commonly used for construction work of
ordinary as well as important buildings and other structures in areas
where natural stone is not obtainable cheaply and abundantly but there
is plenty of suitable clay for the manufacture of bricks.

3. BRICK BONDING
3MAIN THEME
BRICK BONDING
The term bonding is originated from the word Bond. Bonding is the process of
arranging bricks in different courses in order to tie them together in unified mass
of brickwork. Bonding is done to ensure that vertical joints do not come over one
another because having continuous vertical joints will not act as a unified mass
but will act as columns.
PURPOSE
The purpose of bonding in brickwork is to develop longitudinal and transverse
interlocking for individual bricks so as to achieve a unified mass of the structure. If
a wall is properly bonded then the load will be distributed in a uniform way and
the structure did not collapse.

4. For a good bonding, all the bricks should be of
uniform size and shape, the arrangement of laying
bricks must be uniform, all the horizontal joints
must be truly horizontal and vertical joints must be
truly vertical, the vertical joints or perpends should
be vertically above each other in the alternate
courses, and the Centre of the header in each
course should be in the same vertical line as the
Centre of the stretcher lying in the course
immediately above or below it.

6. TYPES OF BRICK BOND
6BRICK BOND
English Bond
The bond having headers and
stretchers laid in alternate
courses is called English bond.
It is commonly adopted for
brickwork of buildings where
strength is of prime
importance.
.
Flemish Bond
bond having headers and
stretchers laid alternately in
the same course is called
Flemish bond. It is
commonly used in the
buildings where the
external appearance is of
prime importance
Heading Bond
The bond having all the
bricks laid as headers in
every course of a wall is
called heading bond or
header bond. It is commonly
used for constructing
staining (brickwork) of
wells, footings, corbels,
cornices, etc.
Stretching Bond
The bond having all the
bricks laid as stretchers in
every course is called
stretching bond. It is used
for constructing 10cm, thick
brick partition walls

Garden Wall Bond
The bond used for constructing
compound walls of a garden is
called garden wall bond. It is
used for constructing thick
garden walls, boundary walls,
compound walls, etc. it is also
used for constructing cavity
walls.
Facing Bond
The bond having bricks of
different thickness and
qualities, used for facing
and backing of the wall,
is called facing bond
Dutch Bond
The bond having headers
and stretchers laid in the
alternate courses and every
stretching course started
with ¾ brick-bat is known as
Dutch bond. It is not in
common use.

8. TYPES OF BRICK BONDING

Raking Bond
The bond having all the bricks laid at
an angle to the facing and backing of a
wall is called raking bond. It is used for
architectural finish and for the footings
of high walls.
English Cross Bond
The bond having headers and
stretchers laid in alternate courses, and
a header provided after the quoin
stretcher, in every alternate stretching
course is called English cross bond. It is
not used now-a-days.

9. RULES FOR GOOD BRICK BONDING
9BRICK BONGING
RULES
• Uniform in size.
• Bricks arranged uniformly throughout the wall
. • Bats are used as little as possible
. • The bricks in the interiors of wall laid as headers, that is, across the wall.
• The lap not more than 2 and one-fourth inches
. • The vertical joints in every other course should be vertically over one another.

11. ADVANTAGES OF BRICK MASONRY
The brick masonry is cheaper as compared to stone masonry.
Bonding strength is very good.
In brick work , the mortar joints are thin and hence the structure
becomes more durable.
No complicated lifting devices are necessary in brick work.
Brick work can be done by the less skilled labour also.
In Brick work good quality of bricks posses good fire resistance.
Due to regular size of bricks they are easy to handle.

12. DEFECTS IN BRICK MONOSARY
Sulphate attack Sulphate salts present in
bricks work react with alumina content of
cement . It occur in boundary walls
Crystallization of salts from bricks Occur
in masonry made out of brick which
contain excessive soluble salts This
phenomenon is also known as
efflorescence.
Corrosion of embedded iron or steel Iron
or steel embedded in brick work gets
corroded in the presence of dampness
On corrosion the metal expands in
volume and tends to crack the brick work
