This set of Construction and Building Materials Multiple Choice Questions & Answers (MCQs) focuses on “Bonds in Brickwork”.
1. In ___________ type of bond, all the brakes are arranged in the stretcher courses.
a) English bond
b) Header bond
c) Stretcher bond
d) Flemish bond
View Answer
Explanation: The stretcher bond is useful for one brick partition walls as there are no headers in such walls. As this bond does not develop proper internal bond, it should not be used for walls having thickness greater than that of one-brick wall.
2. In ____________ type of bond, all the bricks are arranged in header courses.
a) Header bond
b) Flemish bond
c) Dutch bond
d) Facing bond
View Answer
Explanation: Header bond does not have strength to transmit pressure in the direction of the length of the wall. Hence it is not suitable for load bearing walls. However, this bond is used for curved surfaces in the brick work because stretches, if used for curved faces, would project beyond the face of the wall.
3. __________ bond is considered as the strongest Bond in brick work.
a) English bond
b) Raking bond
c) Garden-wall bond
d) Dutch bond
View Answer
Explanation: English bond is generally used in practice. In English bond, the alternate courses consist of stretches and headers, the queen closer is put next to the queen header to develop the face slap and each alternate header is centrally supported over a stretcher.
4. In _______ type of bond, the headers are distributed evenly.
a) Stretcher bond
b) Flemish bond
c) Header bond
d) English bond
View Answer
Explanation: In Flemish bond, the headers are distributed evenly and hence, it creates a better appearance than the English bond. In Flemish Bond, in every course, the headers and stretchers are placed alternately. Here, the Quoin closer is put next to the Quoin header in alternate courses to develop the face lap.
5. In the ________ bond, one header course is provided after three or five stretcher courses.
a) English cross bond
b) Facing bond
c) Raking bond
d) Garden-wall bond
View Answer
Explanation: As the name suggests, the Garden-wall bond is used for the construction of the boundary walls, compound walls, Garden walls, etc. The wall is one brick wall and its height does not exceed 2 metres. The wall my may be constructed either in English bond or Flemish bond.
6. The __________ bonds are used when was become weak in the longitudinal direction due to filling of thicker wall in the headers only.
a) Dutch bond
b) Facing bond
c) Raking bond
d) English cross bond
View Answer
Explanation: As the filling of thicker wall is done by headers only, such wall become weak in the longitudinal direction. The raking on inclined bonds are used in such cases as remedial measures. The raking or inclination should be in opposite direction in alternate courses of the Raking bond.
7. __________ is a modified form of English bond and by this bond, the corner of the walls is strengthened.
a) Dutch bond
b) Brick-on-edge bond
c) Facing bond
d) Flemish bond
View Answer
Explanation: In Dutch bond, the alternate courses are of headers and stretchers, the Quoin of a stretcher course is a three quarter but and a header is introduced next to the three quarter bat in every alternate stretcher course.
8. In _______ type of bond, the brakes are laid on edge instead of bed.
a) English cross bond
b) Brick on-edge bond
c) Raking bond
d) Dutch bond
View Answer
Explanation: Brick-on-edge bond is economical and as it consumes less number of bricks and less quantity of mortar. It has however not strong and hence easily is used for the construction of Garden walls, compound walls, partition walls, etc.
9. _______ is another modified form of the English bond and it is used to add beauty in the appearance on the wall.
a) Brick-on-edge
b) Facing bond
c) Garden wall bond
d) English cross bond
View Answer
Explanation: The elevation of a wall with English cross Bond is also known as the St. Andrews Cross bond. In this bond, the alternate courses are of headers and stretchers, the queen closer as are place next to the Quoin header and a header is introduced next to the Quoin Stretcher in every alternate stretcher course.
10. In ________ type of bond, a header course place after several Stretcher courses.
a) Header bond
b) Stretcher bond
c) Flemish bond
d) Facing bond
View Answer
Explanation: If the facing and backing bricks vary in size and shape, the facing bond is adopted. The least common multiple of the thickness of facing and backing bricks decides the distance between the successive header courses. If the facing bricks are expensive and if it is desired to economise, the facing bond is adopted.
