Definition
Composite masonry use to two reasons
Following types
(1) Stone slab facing with brick backing
(2) Stone facing and brick backing
(3) Brick facing and concrete backing
(4) Ashlar facing and brick backing
(5) Ashlar facing and rubble backing
DefinitionComposite masonry is the one which
is constructed out of two or more types of
building units or of different types of
building materials.

The composite masonry may
be adopted due to two
reasons :1 :- improvement in the
appearance of walls etc.,
2 :- use of available
materials,to obtain optimum
economy.
Composite masonry may be of
the following types :
Stone slab facing with brick backing
ii. Stone facing and brick backing
iii. Brick facing and concrete backing
iv. Ashlar facing and brick backing
v. Ashlar facing rubble backing
i.

In this type of composite masonry, the
stone slab are used in the face work and
brick masonry is used as backing the
stone used may be natural or artificial.

The stone slab are secured to the
backing either by means of metal cramps
or by projecting the headers in the face
work well inside the backing.

The number of joints in the backing
may be more then the joints in the facing
and therefore the bonding between to
faces should be perfect to avoid unequal
settlement of the two leaves.

In this type of composite masonry, a
wall is constructed in brick work and the
stones are provided on facing , to appear
as if the wall is constructed in stones.
It is adopted to improve the
appearance of the structure or wall
at a lesser cost.

The stones are properly secured
to brick backing by providing
toothing.


In this type of composite masonry, the
bricks are used as the facing material
and the concrete is used as backing.

this type of construction is adopted to
get the strength of the concrete and to so
the wall face, as if constructed with
bricks.
 The bricks are secured to the backing
by projecting alternate brick headers into
the concrete.

In this type of composite masonry the face of
stones are rough tooled and the chamfered and
the stones are provided in the face work only.

the backing may be mead in brick. This
type of construction reduces the cost of
work considerably.
The height of the course is always more
then 20 cm and the width of each stone
is about 1*1/2 times its height.
 For walls up to 75 cm in thickness ,the
bond stones should extend for full
thickness of the wall.
In this type of composite masonry the
faces of the stone are rough tooled and
the chamfered and the stones are
provided and face work only.

The backing may be made of rubble.
This may reduce the cost of
construction, as the rubble stones are
available at cheap rate.
The stones are secured to the backing
either by means of metal cramps or by
projecting the heading in the face work
well inside the backing.
