1. Brick Masonry
Brick Masonry may be defined as the laying of bricks in a
systematic pattern , bonded with mortar to form a well
united mass.

2. Advantages of Masonry
Bricks are light in weight and convenient in size
They can be easily handled by mason by one hand
They can be manufactured at all the sites and are easily
available
Due to light weight properly, they do not require any
lifting appliances
As they are uniform in size, they can be used in definite
set pattern termed as bonds
Like stone block they do not require any dressing

3. Principle In Brick Masonry
Construction
• In brick masonry work , the bricks used should be sound ,
hard , well burnt with uniform size , shape and color.
• The bricks should be free from all types of defects like holes ,
cracks , flaws , air bubbles , stone lumps , lime lumps , over
burnt etc .
• To ensure proper bond between old and new brick work, the
walls should be stopped with the toothed end
• When the mortar is in green stage, the joints should be
properly flushed and filled with mortar so that no cavity is left
in between

4. Technical Terms In
Brick Masonry
• Brick: A brick is a block or a single
unit of a ceramic material used in
masonry construction
• Header: The face of brick showing
breadth and height of brick is
termed as header
• Stretcher: The face of brick
showing length and height of brick
is termed as stretcher
• Frog: The depression provided on
the top face of the brick during its
manufacturing is termed as frog
• Course: Each horizontal layer of
bricks, laid in mortar in brick
masonry construction is known as
course
• Bond; The process of arranging
bricks with mortar to tie them
together in a mass of brick work is
termed as bonding

5. The Procedure for Building Brick Walls
The procedure for building brick walls. This example is a single wythe of running bond.
（A）The construction of a brick wall begins with the laying of leads. The leads establish
the wall planes and course heights
（B）The bricks between the leads are laid to a line, a heavy string stretched taut between
line blocks at each lead
（C）When the entire wall is laid to the level of the top of the leads, a second set of leads is
laid, and the entire process is repeated as many times as necessary

6. Bonds In Brick Masonry
• Bonding is a process of arranging bricks
with cement , sand , mortar to tie them
together in a solid mass of brick work. the
bricks are arranged in courses and
bonded together ,to act as a single unit
for carrying load.

7. Different Types of Bond

8. Method of bonding New Brick work with old
When it is desired to increase the length of the wall under
construction at a future date, the wall should be stopped with a
toothed end. It is necessary to ensure continuous bonding between
the old and the new brick.
Raking Back: In rising the corner,
the courses end in a series of
steps in order that the men on
the wall may place the courses to
it in the easiest manner. In simple
words, each course on the wall
will be shorter than the course
below it.
Block Bonding: It is used in
situations where a new wall is to
be tied into an existing wall, but
where appearance is of no
importance. This method is
trying in a wall is similar to
toothing with the exception that
three to five courses are cut out
to form the tie.

9. Expansion and Contraction joint
Expansion joints are provided to allow free expansions
of the structure due to increase in temperature. If
these joints are not provided at suitable intervals, then
the structure shall subjected to internal compressive
stresses. These stresses can cause the failure of
structure.

10. Reinforced Masonry Walls
It may be either a solid
masonry wall or a masonry
cavity wall. Reinforced
Masonry Walls Load
bearing masonry walls
may be built with or
without reinforcing.
Unreinforced walls cannot
carry such high stresses
as reinforced walls and are
unsuitable for use in
regions with high seismic
risk, but such walls have
been used in the United
States to support buildings
as tall as 16 stories.
