1. Which of the following is not a type of partition wall?
a) Brick partitions
b) Glass partitions
c) Gum partitions
d) Concrete partitions
Answer: c
Clarification: A partition wall is a type of wall which is used to divide the space within the building. It is of the following types – brick partitions, glass partitions, concrete partitions, metal lath partitions, plaster slab partitions, timber partitions, etc.
2. Which of the following is an important requirement in the design of internal walls?
a) Thermal insulation
b) Sound insulation
c) Weather exclusion
d) Heat
Answer: b
Clarification: Sound insulation is an important requirement in the design of internal walls. An internal wall is a load-bearing partition wall. Strength is also an important factor in the design of internal walls.
3. Partition walls are load-bearing walls.
a) True
b) False
Answer: b
Clarification: Partition walls can be either load-bearing or non-load bearing. Partition walls are generally non-load bearing walls.
4. A partition wall should be _______
a) Heavy and thick
b) Light and thick
c) Light and thin
d) Light and thick
Answer: c
Clarification: A partition wall should be as light and as thin as possible. Lighter the partitions, the lighter will be the structural elements. This will result in a better economy of the building.
5. Which of the following is a requirement which must be filled by partition walls?
a) A partition wall should be heavy
b) A partition wall should be fire resistant
c) A partition wall should be thick
d) A partition wall may not act as a sound barrier
Answer: b
Clarification: Some of the requirements that must be filled by partition walls are they should be light and thin. They must act as a sound barrier. They should be fire resistant and strong enough to carry their own load.
6. Hollow clay blocks used for clay block partition walls are not _________
a) Good insulator of heat
b) Good conductor of heat
c) Good insulator of sound
d) Fire-resistant
Answer: b
Clarification: For the construction of clay block partition walls, hollow clay blocks may be used. They are good insulators of heat and sound. They are also fire-resistant.
7. In hollow clay blocks used for clay block partition walls ___________ serve as a key to plaster.
a) Grooves
b) Frog
c) Arris
d) Kick
Answer: a
Clarification: In hollow clay blocks used for clay block partition walls, grooves serve as a key to plaster. Grooves are provided on the top, bottom and sides of the blocks. A frog is an indentation in the brick for holding the mortar. An arris is an edge of a brick. A kick is another term used for a frog.
8. In concrete partitions, concrete mix adopted for precast slab units is _________
a) M 10
b) M 15
c) M 20
d) M 25
Answer: b
Clarification: In concrete partitions, concrete mix adopted for precast slab units is usually M 15. In M 15, M denotes Mix and 15 is the characteristic compressive strength of concrete cube at 28 days in N/mm2.
9. The thickness of cast-in-situ concrete partitions is generally ___________
a) 80-100 mm
b) 80-100 cm
c) 40-60 mm
d) 40-60 cm
