--ADVANTAGES OF BRICK MASONRY
► 1'he Brick masonry is cheaper than
compared to stone masonry.
► Bricks are of uniform size.
► Bricks are very workable .
► Brick blocks don't need any dressing.
► Bricks are very light in '\ffight.
► No complicated lifting devices are
necess.u:y in brick work.
► There is no problem to its availability.
► They do not require transportation from
long distances,
► Brick work can be done by the less skilled
labollll'S also.
► Bonding strength is very good and brick
work is more durable.

• Thesurface & edges are rough.
• Does not create any metallic sound.
• Used for temporary & unimportantstructure.
U FOURTI-1 CLASS BRICKS:-
• This bricks a.re over brunt.
• Irregularshape & dark rolour.
• Used in floor , foundation, roads.
MANUFACTURING OF BRICKS
• Raw materials like Fly ash, lime sand and gypsum OR
Fly Ash, Cement & Sand are manually fed into a pan
m ix:er where water is added in the required proportion
for intimate mixing. The proportion of the raw material
is generally in the ratio 60-80% of fly ash, 20-25% sand
and 8-10% Cement OR 60-80% of fly ash 10-20% lime,
10% Gypsum and 10% sand, depending upon the
quality of raw materials.
• After mixing, the mixture is shifted to the
hydraul ic/mechanical presses. The bricks are carried on
wooden pellets to the open area where they are dried
and water cured for 21 days. The bricks are tested and
sorted before dispatch.

INTRODUCTION
, Brick bonds are an essential part of
wall structure.
, "brick" is a standard-sized \veight-
bearing building unit.
, Several bricks are laid together in
stacks.
, Mortar paste is placed on top of
each to form a firm bond.
, are laid to fonn the structure.
, There are different '-''ays in which
bricks are termed as bonds.
DEFECTS IN BRICK MASONRY
□Sulphate attack :- Sulphate salts present in bricks
work react with alumina content of cement .It occur in
boundarywalls.
□Crystallization of salts &om 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.

► Brick masonry increases the

Masonry tends to be heavy
and must be built upon a
strong foundation, such as
reinforced concrete, to avoid
settling and cracking.
GARDEN-WALL BOND
► Used for 9 inch wall.
► Used when a fair face is
required on both sides.
► Wall is composed of three or
four courses of stretchers
alternating with one of
headers.
► It is mostly used in
construction of garden wall.
