1. What is the primary purpose of a mortar joint in masonry construction?
A. To increase the weight of the wall
B. To bond masonry units together and transfer loads
C. To eliminate the need for reinforcement
D. To prevent all moisture from entering the wall
Answer: To bond masonry units together and transfer loads
Rationale: Mortar bonds masonry units, accommodates minor dimensional
variations, and transfers compressive and shear forces between units.
2. Which mortar type generally provides the highest compressive strength?
A. Type O
B. Type N
C. Type S
D. Type M
Answer: Type M
Rationale: Type M mortar has the highest compressive strength among the
commonly specified ASTM mortar types and is typically used where high
compressive strength is required.
3. What is the primary purpose of tooling a mortar joint?
,A. To remove all mortar from the joint
B. To improve the appearance and compact the mortar at the surface
C. To make the wall heavier
D. To increase the size of the masonry units
Answer: To improve the appearance and compact the mortar at the surface
Rationale: Proper joint tooling compresses the mortar surface and helps create a
more weather-resistant joint while producing the desired appearance.
4. Which joint profile generally provides good resistance to water
penetration?
A. Concave
B. Raked
C. Flush
D. Struck
Answer: Concave
Rationale: A properly tooled concave joint compresses the mortar and sheds
water effectively, making it one of the preferred profiles for exterior masonry.
5. What is the primary function of masonry reinforcement?
A. To replace mortar
B. To improve resistance to tensile and lateral forces
C. To reduce wall height
D. To eliminate control joints
Answer: To improve resistance to tensile and lateral forces
Rationale: Masonry is strong in compression but relatively weak in tension.
Reinforcement improves its ability to resist tensile, bending, and lateral stresses.
6. What is a bond beam?
,A. A temporary wooden support
B. A reinforced horizontal masonry member
C. A decorative mortar joint
D. A type of masonry saw
Answer: A reinforced horizontal masonry member
Rationale: Bond beams are typically reinforced and grouted to provide
horizontal structural continuity and distribute loads through masonry walls.
7. What is the purpose of grout in reinforced masonry?
A. To lubricate masonry units
B. To surround reinforcement and bond it to the masonry assembly
C. To replace all mortar joints
D. To waterproof the face of the wall
Answer: To surround reinforcement and bond it to the masonry assembly
Rationale: Grout fills reinforced cells and other designated spaces, embedding
reinforcement and helping transfer stresses between the reinforcement and
masonry.
8. Which tool is commonly used to check whether a wall is vertically aligned?
A. Level
B. Jointer
C. Trowel
D. Brick hammer
Answer: Level
Rationale: A level is used to check plumb and level conditions. Masonry walls
must be kept within specified tolerances as construction progresses.
9. What does the term "plumb" mean in masonry construction?
, A. Perfectly horizontal
B. Properly finished
C. Vertically aligned
D. Fully grouted
Answer: Vertically aligned
Rationale: A wall or other masonry element is plumb when its vertical surfaces
are aligned correctly with the true vertical.
10.What does "course" mean?
A. A row of masonry units
B. A mortar mixing procedure
C. A type of reinforcement
D. A masonry tool
Answer: A row of masonry units
Rationale: A course is a horizontal layer or row of masonry units, such as brick,
block, or stone, laid in a wall.
11.What is a wythe?
A. A vertical section or layer of masonry units
B. A mortar mixing ratio
C. A type of scaffold
D. A finishing tool
Answer: A vertical section or layer of masonry units
Rationale: A wythe is a continuous vertical section of masonry one unit in
thickness or greater, depending on the construction system.
12.Why are masonry units sometimes wetted before installation?
A. To make them heavier
B. To control absorption under specified conditions
