1. In _______ type of construction, the stones of irregular sizes are used.
a) Rubble masonry
b) Ashlar masonry
c) Brick masonry
d) Granite masonry
Explanation: In Rubble masonry, the stones, as obtained from quarry, are taken in use in the same form or they are broken and shaped in suitable sizes by means of hammer as the work proceeds. The strength of rubble masonry mainly depends on the quality of mortar and the use of long through Stone at frequent intervals.
2. In _______ masonry, the stones of irregular sizes and shapes are used which are arranged so as to have a good appearance.
a) Dry rubble masonry
b) Polygon rubble masonry
c) Random rubble masonry
d) Uncoursed rubble masonry
Explanation: In Random rubble masonry, the face stones are chisel addressed and the thickness of mortar joints does not exceed 6 mm. This type of masonry is used for the construction of residential buildings, compound walls, godowns, etc.
3. In _________ type of construction, the square or rectangular blocks of stones are used.
a) Brick masonry
b) Rubble masonry
c) Rock Masonry
d) Ashlar masonry
Explanation: In Ashlar masonry, the height of stone various from 250 mm to 300 mm. The length of stone should not exceed 3 times the height and the depth into the wall should be at least equal to half the height.
4. 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
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.
5. In ____________ type of bond, all the bricks are arranged in header courses.
a) Header bond
b) Flemish bond
c) Dutch bond
d) Facing bond
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.
6. __________ bond is considered as the strongest Bond in brick work.
a) English bond
b) Raking bond
c) Garden-wall bond
d) Dutch bond
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.
7. In _______ type of bond, the headers are distributed evenly.
a) Stretcher bond
b) Flemish bond
c) Header bond
d) English bond
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.
8. 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
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.
9. 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
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.
10. __________ 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
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.
