In brick masonry the bond produced by laying alternate headers and stretchers in each course is known as

Solution(By Examveda Team)

In brick masonry, various types of bonds are used to enhance the structural integrity and aesthetic appeal of the construction. Let's examine each option:

Option A: English bond - This bond is formed by laying alternate courses of headers and stretchers. Headers are bricks laid with their ends facing outwards, while stretchers are bricks laid with their faces parallel to the face of the wall. This pattern provides good strength and stability to the wall, making it a commonly used and efficient bond in brick masonry.

Option B: Double Flemish bond - This bond consists of alternate courses of stretchers and headers, with each header being centered over the stretcher below it and vice versa. This creates a pattern of alternating headers and stretchers on each face of the wall. While the double Flemish bond is visually appealing and offers good strength, it requires more skill and effort to construct compared to the English bond.

Option C: Zigzag bond - This bond involves the use of bricks laid in a zigzag pattern, with each course consisting of bricks laid diagonally or at an angle to the face of the wall. While the zigzag bond may provide some decorative effects, it lacks the structural integrity and stability offered by bonds such as the English bond.

Option D: Single Flemish bond - This bond is similar to the double Flemish bond but with only one header placed over each stretcher and vice versa. While the single Flemish bond is easier to construct compared to the double Flemish bond, it still requires more skill and effort than the English bond. Additionally, it may not provide as much strength and stability as the English bond due to the lack of headers in every course.

Conclusion:
Among the options provided, Option A: English bond is the correct choice for a bond produced by laying alternate headers and stretchers in each course. It offers a balance of structural integrity, stability, and ease of construction, making it a widely used and effective bond in brick masonry.
