1. 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
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.
2. _______ 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
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.
3. In ________ type of bond, a header course place after several Stretcher courses.
a) Header bond
b) Stretcher bond
c) Flemish bond
d) Facing bond
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.
4. A connection between a main wall and partition wall is termed as __________
a) Bond
b) Joint
c) Junction
d) Bed
Explanation: In a Junction, the header course of the cross wall will enter the stretcher course of the main wall and the alternate course of the cross wall are simply abutting the main wall. Injunction is classified into two categories – right angled junction and squint Junction.
5. ________ type of right angle junction forms the shape of the English letter T in plan.
a) Tee-junction
b) Cross-junction
c) Squint junction
d) Brick junction
Explanation: In Tee-junction, alternate courses of tee junction between one brick external wall and half brick internal wall, both the walls being constructed in English bond. One of the courses of the internal wall enters the stretcher course of the main wall, creating a lap of half brick.
6. A ___________ junction is formed when two continuous walls cross or intersect each other.
a) Squint junction
b) Cross-junction
c) Obtuse squint
d) Right angled junction
Explanation: In Cross-junction or an Intersection, the alternate courses of the cross wall i.e. the courses of one of the walls simply butt against the courses of the other wall. Also, the alternate courses which are not continuous are provided with tie bricks in the form of key headers to create the necessary bond and lap.
7. A ________ is formed when two walls meet each other at an angle other than a right angle without making a quoin.
a) Cross-junction
b) Squint junction
c) Quoin
d) Intersection
Explanation: Squint junction may be in the English bond and Flemish Bond. The Squint junction is however not common in brickwork and it is rarely adopted because great difficulties experience in accurately forming it in practice.
8. ________ form of quoin is formed when two walls meet at an angle of 90°.
a) Square quoin
b) Squint quoin
c) Acute quoin
d) Obtuse quoin
Explanation: As the term implies, right-angled or square quoin is the form of quoin which is formed when two walls meet an angle of 90°. In right angled quoin, at the same level, header course on one face of angle is converted into a stretcher course on the other face of the angle. No vertical continuous joints are formed in this type of quoin.
9. A _________ is formed when a wall takes a turn and makes an angle other than a right angle.
a) Right angled junction
b) Acute squint
c) Squint quoin
d) Right angled quoin
Explanation: In Squint quoin, the continuous straight joint should be avoided, the maximum length should be obtained with the maximum cutting of the bricks and the number of broken bricks to be used should be reduced to a minimum
10. In ______ the in closed angle on the inside of the wall is less than a right angle.
a) Acute quoin
b) Acute squint
c) Squint quoin
d) Obtuse squint
Explanation: In Acute squint, the enclosed angle on the inside of the wall is less than 90°. An acute squint can be in the form of an English bond or in the double Flemish bond.
