10. Different Type of Bricks

11. Commonly Used Bonds are: -Stretcher Bond -Header Bond -English Bond -Flemish Bond Types of bonds in brickwork In brick masonry bond is the arrangement of bricks in each layer to avoid the continuity of vertical joints in any two adjacent courses. Brick bonding is the pattern in which bricks are arranged in a structure such as a wall or column. Bonds in brickwork

12. Stretcher Bond: Stretcher Bond, also called as running bond, is created when bricks are laid with only their stretchers showing. Bonds in brickwork A header is the shorter face of the brick as seen in the elevation. In header bond brick masonry all the bricks are arranged in the header courses .

13. English Bond: English bond is a pattern formed by laying alternate courses of stretches and headers. Bonds in brickwork

14. Flemish Bond: In this type of bond, each courses consists of header and stretchers alternatively arranged. Bonds in brickwork
