Brick Bonds – Appropriate bond for a 10 cm thick (half-brick) partition wall For constructing a 10 cm thick internal partition wall (approximately half-brick thick), which brick bond is most appropriate?

AEnglish bond
-
BFlemish bond
-
CHeader bond

DStretcher bond
-
ERat-trap bond
Answer
Correct Answer: Stretcher bond
Explanation
Introduction / Context:Brick bonds control strength, stability, and appearance. Half-brick partition walls (about 100–115 mm thick depending on brick size) are non-loadbearing and are typically laid to maximize speed and face finish using continuous stretcher courses.
Given Data / Assumptions:
- Wall thickness ≈ 10 cm (half-brick).
- Internal partition, generally non-loadbearing.
- Standard modular bricks laid with mortar joints.
Concept / Approach:Stretcher bond consists of bricks laid with the long face (stretcher) exposed, course after course, with half-brick overlaps. Header or English/Flemish bonds require full-brick thickness to interlock headers, which is not possible in half-brick walls.
Step-by-Step Solution:Identify wall as half-brick thickness.Choose bond that does not require through headers: stretcher bond.Exclude bonds designed for one-brick thickness (≈ 20–23 cm) or more.
Verification / Alternative check:Specifications for non-loadbearing partitions routinely prescribe stretcher bond, sometimes with reinforcement (e.g., at every third or fourth course) to control cracking.
Why Other Options Are Wrong:
- English/Flemish/header bonds need headers across wall thickness; not feasible in half-brick thickness.
- Rat-trap bond creates cavities and uses brick on edge; not standard for 10 cm plain partitions.
Common Pitfalls:Assuming decorative Flemish bond can be used in half-brick partitions; true interlocking requires greater thickness.
Final Answer:Stretcher bond
