Brick Masonry Definition :-Construction of brick units bonded together with mortar is termed as brick masonry.
The strength of the brick work primarily depends upon quality and strength of the brick, the type of
mortar and the method of bonding, adopter in construction. Brick can be divided into two types.
Types of Brick
Traditional Brick
Modular Brick
1. Header -It is a full brick which is laid
with its length perpendicular to the face of the wall. Its face measuring 10x10 cm.
2. Stretcher – It is a full brick or stone
which is laid with its length parallel to the face of the wall. Its face measuring 10x20 cm.
3. Full Brick - It is a full brick . The normal
size of the full brick is 19x9x9cm.
4. Half Bat -It is the portion of a brick cut
across the width or a brick cut by half of its length.
5. King closer - It is a brick which is cut in
such a way that the width of one of its end
is half that of a full brick.
6. Bevelled Closer- It is similar to king
closer with the only difference that the whole length of the brick is bevelled for maintaining half width width at the other.
7. Perpend- It is a vertical joint on the
face of a wall directly over vertical joints in alternate course.
8. Mitred Closer -It is a brick whose one
end is cut mitred for the full width.

Brick Masonry Types of brick bond
1.Header bond :-All the bricks are laid as
headers on the faces. The overlap, which is usually of half the width of the brick is obtained by introducing a three quarter bat in each alternate course at quoins and used for walls
curved on plan.
2.Stretcher bond:- All the bricks are laid as
stretchers. The overlap, which is usually of half brick, is obtained by commencing each alternate course with a half brick bat. Stretching bond is used for half brick wall only.
3.English bond:- This bond consists of
alternate course of headers and stretches. In this arrangement, vertical joints in the header courses come over each other and the vertical joints in the stretcher course are also in the same line.
4.Flemish bond:- In this arrangement of
bonding brick work, each course consists of alternate headers and stretchers. The alternate headers of each course are centered over the stretchers in the course. Every alternate course starts with a header at the corner.
5.Garden wall bond:- The type of bond is
suitably adopted for one brick thick wall which may act as a garden wall or a boundary wall.

Definition of brick bonds
This type of bond is not so strong as English
bond & its use is restricted to construction of dwarf walls. These are in two types viz English & Flemish Garden wall bond.
6. English cross-bond:- This is similar
to English bond and consists of alternate course of headers and stretchers. However, in this bond, queen closer are introduced next to quoin headers and each alternate stretching course has header placed next to quoin stretcher.
7. Facing bond:- This arrangement of
brick is adopted for thick walls, where the facing and backing are desired to be constructed with bricks of different thickness.
8. Raking bond:- This is a bond in brick
work in which the bonding bricks are laid at any angle other than zero or ninety degrees.
9. Dutch bond:- This bond is a
modification of the old English cross bond and consists of alternate courses of headers and stretchers.
10. Zig-Zag bond:- This is similar to
herring bone bond with the only difference that in this case the bricks are laid in a zig-zag fashion. This is commonly adopted in brick paved flooring.
