1. What is the primary purpose of mortar in masonry
construction?
A. To waterproof the wall completely
B. To bond masonry units and distribute loads
C. To replace reinforcement
D. To increase the weight of the wall
Answer: B. To bond masonry units and distribute loads
Rationale: Mortar bonds masonry units together,
accommodates minor dimensional variations, and helps
distribute loads between units.
2. Which material is commonly used as the primary binder in
modern masonry mortar?
A. Portland cement
B. Gravel
C. Sand
D. Clay
Answer: A. Portland cement
Rationale: Portland cement provides hydraulic binding
properties that allow mortar to harden when mixed with water.
,3. What is the main purpose of sand in mortar?
A. To act as aggregate and control shrinkage
B. To provide waterproofing
C. To replace cement
D. To accelerate curing
Answer: A. To act as aggregate and control shrinkage
Rationale: Sand forms the bulk of mortar and helps control
shrinkage and workability.
4. What does adding too much water to mortar generally do?
A. Increases final strength
B. Improves durability
C. Reduces strength and may increase shrinkage
D. Eliminates curing requirements
Answer: C. Reduces strength and may increase shrinkage
Rationale: Excess water can increase porosity and shrinkage,
reducing the hardened mortar's performance.
5. Which tool is commonly used to spread mortar on a
masonry unit?
A. Mason's trowel
B. Pipe wrench
C. Hacksaw
D. Leveling rod
,Answer: A. Mason's trowel
Rationale: A mason's trowel is designed to pick up, spread, and
shape mortar during masonry installation.
6. What is the purpose of a masonry line?
A. To measure mortar temperature
B. To establish a straight reference for laying units
C. To cut brick
D. To test compressive strength
Answer: B. To establish a straight reference for laying units
Rationale: A taut mason's line helps maintain straight and
properly aligned courses.
7. Which instrument is commonly used to check whether a
masonry wall is vertical?
A. Plumb bob
B. Tape measure
C. Chalk reel
D. Brick hammer
Answer: A. Plumb bob
Rationale: A plumb bob provides a vertical reference for
checking plumb.
8. What does a spirit level primarily measure?
, A. Mortar strength
B. Horizontal and vertical alignment
C. Brick absorption
D. Concrete temperature
Answer: B. Horizontal and vertical alignment
Rationale: A level is used to determine whether surfaces are
level and, depending on its orientation, plumb.
9. What is a masonry course?
A. A layer or row of masonry units
B. A type of mortar
C. A foundation footing
D. A masonry tool
Answer: A. A layer or row of masonry units
Rationale: A course is a continuous horizontal layer of masonry
units.
10. What is the primary purpose of staggering vertical mortar
joints?
A. To increase wall weight
B. To improve bonding and distribute loads
C. To reduce mortar use to zero
D. To eliminate expansion joints
