ENGLISH BOND:
English bond is considered as the strongest and most widely used brick bond in construction work. It consists of alternate course of headers and stretchers.
In this arrangement, vertical joints in the header and stretcher courses come over each other. To break the vertical joints in the consecutive courses queen closer should be placed after the first header in every header course.
FLEMISH BOND:
In this brick bond, each course consists of alternate headers and stretchers. Every header is centrally supported over the stretchers below it. To break the vertical joints in the successive courses queen closers are placed in alternate courses next to the queen header. Bats are essentially required for the walls having their thickness equal to odd numbers of half bricks. Flemish bond gives better appearance than english bond.
Flemish bond can be sub-divided into two different categories.
1. Single flemish bond and
2. Double flemish bond.
