1. A mason is preparing to lay concrete masonry units (CMUs) for a wall
at a healthcare facility. Before placing the first course, what is the
most important step to ensure the wall is properly aligned and stable?
A. Applying mortar to the entire wall surface
B. Checking the foundation, layout lines, and elevation measurements
C. Painting the blocks before installation
D. Filling all blocks with concrete immediately
Answer: B. Checking the foundation, layout lines, and elevation
measurements
The first course determines the alignment, level, and stability of the entire
masonry wall. Proper layout, elevation checks, and foundation inspection
prevent defects that become difficult to correct later.
2. Which mortar type is commonly used for general-purpose masonry
construction because it provides a good balance of strength,
workability, and durability?
A. Type M mortar
B. Type S mortar
,C. Type N mortar
D. Type O mortar
Answer: C. Type N mortar
Type N mortar is widely used for above-grade exterior and interior
masonry because it provides adequate compressive strength while
maintaining good flexibility and workability.
3. When laying bricks, what tool is primarily used by a mason to spread
mortar and shape mortar joints?
A. Brick hammer
B. Mason’s trowel
C. Plumb bob
D. Masonry saw
Answer: B. Mason’s trowel
A mason’s trowel is designed to pick up, spread, and shape mortar during
brick and block installation, making it one of the most essential masonry
tools.
4. A mason uses a level during wall construction primarily to verify which
condition?
A. The color consistency of bricks
B. The moisture content of mortar
C. The horizontal and vertical alignment of masonry
D. The weight of masonry units
Answer: C. The horizontal and vertical alignment of masonry
A level helps ensure that masonry courses are horizontal (level) and walls
are properly aligned vertically (plumb), preventing structural and
appearance problems.
, 5. What is the purpose of tooling mortar joints after masonry units are
placed?
A. To increase the size of the masonry units
B. To compress and finish the mortar surface for durability and appearance
C. To remove all mortar from the wall
D. To prevent bricks from bonding together
Answer: B. To compress and finish the mortar surface for durability and
appearance
Tooling compresses mortar joints, improves weather resistance, reduces
water penetration, and creates a finished appearance.
6. Which masonry material is manufactured by firing clay in a kiln?
A. Concrete block
B. Brick
C. Stone veneer
D. Portland cement
Answer: B. Brick
Brick is produced by shaping clay and firing it at high temperatures, which
creates a durable masonry unit used in many construction applications.
7. When constructing a masonry wall, what does the term “plumb”
mean?
A. The wall is perfectly horizontal
B. The wall is perfectly vertical
C. The mortar is completely dry
D. The bricks are the same color
Answer: B. The wall is perfectly vertical
, A plumb wall is vertically aligned. Masons use tools such as levels and
plumb bobs to maintain proper vertical accuracy.
8. Which safety equipment is most appropriate when cutting masonry
units with a saw?
A. Hearing protection and safety glasses
B. Cotton gloves only
C. Sandals and protective eyewear
D. Loose clothing and no mask
Answer: A. Hearing protection and safety glasses
Masonry cutting creates noise and flying particles. Proper protective
equipment reduces the risk of eye injuries and hearing damage.
9. What is the main purpose of reinforcing steel placed inside concrete
masonry walls?
A. To change the wall color
B. To increase structural strength and resistance to loads
C. To reduce mortar usage
D. To make blocks lighter
Answer: B. To increase structural strength and resistance to loads
Reinforcing steel strengthens masonry walls by improving their ability to
resist tension, bending, and structural forces.
10. A mason notices that a brick wall is leaning during construction.
Which tool should be used first to check the problem?
A. Tape measure
B. Plumb level
C. Wheelbarrow
D. Mortar hoe
