Difficulty: Easy
Correct Answer: In English bond, stretchers are laid in every course.
Explanation:
Introduction / Context:
Bonding patterns control strength, appearance, and joint distribution in brick masonry. English and Flemish bonds are the most cited in examinations and practice. Understanding their coursing rules avoids errors at site and during quantity takeoff.
Given Data / Assumptions:
Concept / Approach:
English bond is defined by alternate courses—one entire course of headers followed by one entire course of stretchers. Flemish bond alternates header and stretcher within the same course, repeating across the wall length, with queen closers at returns to maintain bond. Therefore, any statement that claims “English bond has stretchers in every course” contradicts the definition.
Step-by-Step Solution:
Verification / Alternative check:
Standard diagrams in masonry texts and IS code illustrations confirm the coursing and the need for closers in both bonds to maintain lap at quoins.
Why Other Options Are Wrong:
Options A, B, and D are consistent with standard practice; Option E (“None”) is therefore false.
Common Pitfalls:
Omitting queen closers at corners; confusing elevation appearance with plan bond; miscounting course sequence while drafting.
Final Answer:
In English bond, stretchers are laid in every course.
