10mm thick mortar joints are allowed between bricks to
(a) account for variations in brick dimensions
(b) provide uniform contact between adjacent bricks

(d) make the brickwall a monolithic structural element (e) accommodate different strains setup in different

2or 1 brick thick walls n*lish bond is better than
header bond because
3 (a) it is beautiful3 (b) wall is more stable with stretcher courses
