1 Traditional bricks

 

It has not been standardize in size

 

Dimensions varies from place to place

 

Thickness varies from varies from cm to 7.5cm,widthvaries from 10to13 cm and length varies from 20to25 cm

 

2 Modular brick

 

Any brick which is the same uniform size as laid down by

 

bis  The  nominal  size  of  the  modular  brick  is  20cm

 

x10cmx10cm Actual size is 19x9x9

Bonds in brickwork

 

1.     Stretcher bond

2.     Header bond

3.     English bond

4.     Flemish bond

5.     Facing bond

6.     English crossing bond

7.     Brick on edge bond

8.     Dutch bond

9.     Racking bond

10.                        Zigzag bond

11.                        Garden wall bond

 

Stretcher bond

 

The length of the brick its along with the face of the wall. This pattern is used only for those wall which have thickness of half brick

 

Header bond

 

The width of the bricks are thus along the direction of the wall

 

This pattern is used only when the thickness of the wall is equal to one brick

 

English bond

 

It is the most commonly used methodthis bond is considered to be the strongest

 

This bond consist of alternate course of stretchers and headers

 

Alternative courses will show either headers or stretchers in elevation

 

There is nop vertical joint

 

Every alternative header come centrally over the joint between two stretchers in corse in below

 

Since the number of vertical joint in the header course twice the number of vertical joints in stretcher course ,the joints in the header course are made thinner than the joints in the stretcher course

 

Flemish bond

 

Inthis type of course is comprised of alternative headers and stretchers

 

Types of Flemish bond

 

Double Flemish bond

Single Flemish bond

 

Double Flemish bond

 

  Every course consist of headers and stretchers placed alternatively The facing and backing of the wall in each course have the same appearance

 

Single Flemish bond

 

Single Flemish bond is comprised of double Flemish bond facing an English bond backing and hearting in each course

 

Facing bond

 

This bond is used where the bricks of different thickness are to be used in the facing and backing of the wall

 

The nominal thickness of facing brick is 10 cm and that of backing bricks is 9 cm the header course tis provided at a vertical interval of 90 cm

 

English cross bond

 

This is he modification of English bond to improve the appearance e of the wall Brick on edge bond

 

This type of bond uses stret dutch bond
