1. What is the primary purpose of a bond in masonry construction?
a) To improve thermal insulation
b) To increase structural stability
c) To tie bricks together for strength
d) To enhance aesthetic appearance
Rationale: A bond pattern ensures bricks interlock properly,
distributing loads and increasing wall strength.
2. Which type of brick is most commonly used for structural walls?
a) Fire brick
b) Refractory brick
c) Clay brick
d) Engineering brick
Rationale: Clay bricks are widely used for general structural walls
due to their strength and durability.
3. What is the typical thickness of a standard mortar joint in
brickwork?
a) 3 mm
b) 10 mm
c) 25 mm
d) 50 mm
, Rationale: Standard mortar joints are approximately 10 mm thick
to ensure proper bonding and uniformity.
4. What is the primary function of a weep hole in a brick wall?
a) To ventilate the interior
b) To add decorative detail
c) To allow water drainage
d) To anchor the wall to the foundation
Rationale: Weep holes prevent moisture accumulation within
cavity walls by providing an exit for water.
5. Which tool is used to check the alignment and level of brick
courses?

c) To create a decorative effect
d) To finish the top of the wall
Rationale: Header courses span the thickness of the wall,
connecting multiple brick layers (wythes) for stability.
7. Which type of mortar is best suited for high-strength masonry
walls?
a) Type O
, b) Type S
c) Type N
d) Type M
Rationale: Type S mortar has higher compressive strength, suitable
for structural walls subject to higher loads.
8. In brickwork, what is a wythe?
a) A type of mortar
b) A vertical layer of bricks
c) A decorative finish
d) A tool for cutting bricks
Rationale: A wythe is a continuous vertical layer of masonry units
one brick thick.
9. What is the main purpose of control joints in brick walls?
a) To improve aesthetic appeal
b) To control cracking caused by expansion and contraction
c) To reduce wall thickness
d) To facilitate weep hole installation
Rationale: Control joints allow for thermal expansion and
contraction, reducing the risk of random cracking.
10. What is the best practice for soaking bricks before laying?
a) Keep them dry
b) Immerse them in water briefly
c) Heat them in an oven
d) Coat them with oil
Rationale: Soaking prevents bricks from absorbing too much water
from the mortar, ensuring proper bonding.
