1. What is the primary function of mortar in masonry
construction?
A. To waterproof the structure
B. To bond masonry units together
C. To increase the weight of the wall
D. To replace reinforcement
Rationale: Mortar acts as the bonding agent between bricks,
blocks, or stones and distributes loads evenly across the
structure.
Correct Answer: B
2. Which mortar type has the highest compressive strength?
A. Type O
B. Type N
C. Type S
D. Type M
Rationale: Type M mortar has the highest compressive strength
and is used for heavy loads and below-grade applications.
,Correct Answer: D
3. What tool is commonly used to spread mortar when laying
bricks?
A. Float
B. Brick trowel
C. Mason’s hammer
D. Joiner
Rationale: A brick trowel is specifically designed to spread and
shape mortar during brick laying.
Correct Answer: B
4. Which masonry unit is typically hollow to reduce weight
and allow reinforcement?
A. Clay brick
B. Concrete block
C. Stone block
D. Terra cotta tile
Rationale: Concrete masonry units (CMUs) are hollow, allowing
reinforcement with steel and grout.
Correct Answer: B
,5. What is the standard nominal size of a concrete masonry
unit (CMU)?
A. 8 × 8 × 16 inches
B. 10 × 10 × 20 inches
C. 6 × 6 × 12 inches
D. 12 × 12 × 24 inches
Rationale: The most common nominal CMU size is 8 inches
high, 8 inches deep, and 16 inches long.
Correct Answer: A
6. What does the term “course” refer to in masonry?
A. A type of mortar
B. A horizontal row of masonry units
C. A structural beam
D. A finishing process
Rationale: A course is a continuous horizontal row of bricks or
blocks in a wall.
Correct Answer: B
7. Which bond pattern is most common in brick masonry?
A. Stack bond
B. Running bond
, C. Flemish bond
D. English bond
Rationale: Running bond is the most common pattern, where
each brick overlaps the one below it by half its length.
Correct Answer: B
8. What is the purpose of reinforcement in masonry walls?
A. Improve appearance
B. Increase flexibility and tensile strength
C. Reduce cost
D. Reduce mortar usage
Rationale: Reinforcement improves tensile strength and
resistance to cracking or seismic forces.
Correct Answer: B
9. What material is commonly used as reinforcement in
masonry walls?
A. Copper rods
B. Aluminum bars
C. Steel rebar
D. Wood dowels
Rationale: Steel reinforcement bars (rebar) are used to
strengthen masonry walls.
