Masonry Construction MCQ with answer and solution

Concept

Header bond is constructed with all bricks laid as headers on the face of the wall, making it weak in longitudinal strength and unsuitable for load-bearing walls.

Step-by-step solution

1. Understand the definition of a header bond where all bricks are laid as headers (shorter face exposed). 2. Analyze its structural implications: lack of adequate overlap and longitudinal bond. 3. Conclude that due to this structural limitation, it is not recommended for load-bearing walls.

Explanation

A header bond consists entirely of headers facing the exterior. Because headers have a shorter length along the face of the wall (typically half the length of a stretcher), walls built exclusively with header bonds lack sufficient longitudinal bond strength and are generally not suitable for heavy load-bearing walls.

Why the other options are wrong

A: Header bond lacks adequate longitudinal stability and strength for load-bearing walls. B: While it can be used for curved walls due to shorter brick length, it is primarily limited by load capacity. C: Aesthetic appeal is subjective, but its structural limitation is the primary engineering drawback.

Shortcut

Remember that 'Headers' are meant for cross-strength and thickness (walls of 1 brick or more), but a pure header bond lacks longitudinal continuity, making it unfit for load-bearing applications.

Common mistake

Confusing header bond with stretcher bond or English bond, assuming any brick arrangement can take heavy loads.
