1. BRICK BONDS FLEMISH BOND ASAP 1 ALPNA ROHATGI

2. FLEMISH BOND This is formed by laying headers and stretchers alternately in each course. The headers of each course are centred on the stretchers of the course below. This bond is strong and often used for walls which are two-bricks thick. 2 ALPNA ROHATGI

6. The next course of brick is arranged in such a way that the header lies in the center of the  stretcher in the course below,  i.e., the alternate headers of  each course are in the middle of the stretcher , of course, set below it. In this types of bond , every alternative course of this  Flemish bond starts with a header at the corner . The demerits of using this Flemish bond are that construction of  Flemish bond is complex and requires higher expertise  to lay it on proper place as all  vertical mortar joints need to be associated vertically for best bonding effects. For the changing pattern or breaking of vertical joints  in the successive courses, closers are inserted in alternating courses next to the quoin header. 6 ALPNA ROHATGI

7. The Flemish bonds have a better outward show . However, they are weaker than English bonds for load-bearing in wall construction. Hence, if  the pointing has to be done for brick masonry in wall construction,  then the Flemish bond may be used for a better aesthetic outlook. When the walls have to be plastered,  English bond is the best choice for it. 7 ALPNA ROHATGI

8. The Flemish bonds are classified as: The Single Flemish Bond The Double Flemish Bond 8 ALPNA ROHATGI

9. The Single Flemish Bond The Single Flemish bond is a mixture of Flemish and English bond . During this types of construction, t he face exposed surface of the wall consists of the Flemish bond and the backside surface  of the wall made of by English bond in each course. The smallest thickness essential for a single Flemish bond is one and a half brick thickness. The major point of using a single  Flemish bond is to offer higher aesthetic looks on the front side of the wall surface  with required strength in the brickwork by using an English bond. 9 ALPNA ROHATGI

10. The Double Flemish Bond The Double Flemish Bond has a similar appearance  from both sides of the face in the front and back elevations , i.e., in each course, it consists of alternating stretcher and header. This type of bonding is somewhat weaker than the English bond. 10 ALPNA ROHATGI

16. Difference between English Bond and Flemish Bond English bond Headers and stretchers are laid in alternate courses. Strongest of the types of bonds. Provides rough appearance. Special attention is not required for this bond. Progress of work is more. Costly, no brick bats are used. Skilled labor is not required for its construction. Less mortar is used. Flemish bond Headers and stretchers are laid alternately in each course. Comparatively less strong for walls more than 30cm thick. Provide good appearance. Special attention is required for this bond. Progress of work is less. Economical, as brick bats are used. Skilled labor required for its construction. More mortar is used due to use of bats. 16 ALPNA ROHATGI
