1. A mason working in a healthcare facility is assigned to repair a damaged
concrete walkway that receives heavy pedestrian traffic. Before beginning
the repair, which factor is most important to evaluate to ensure the repair
material will perform properly over time?
A. The color of the existing concrete surface
B. The compressive strength, environmental exposure, and compatibility of
repair materials
C. The number of workers assigned to the project
D. The brand name printed on the concrete bag
B. The compressive strength, environmental exposure, and compatibility of
repair materials
The repair material must be compatible with the existing concrete and
suitable for the loads and environmental conditions it will experience.
,Proper material selection prevents premature failure, cracking, and
deterioration.
2. When laying concrete masonry units (CMUs) for a structural wall, the
mason must maintain proper alignment and level throughout the
work. Which tool is most commonly used to verify that the wall
remains plumb?
A. Brick hammer
B. Mason’s line
C. Spirit level
D. Joint raker
C. Spirit level
A spirit level is used to check whether masonry surfaces are vertically and
horizontally aligned. Maintaining plumb walls is essential for structural
stability and proper appearance.
3. A mason is preparing mortar for brick installation. Which mortar
property is most important for allowing the mortar to spread easily
while maintaining adequate strength after curing?
A. Workability
B. Color uniformity
C. Sand temperature
D. Weight of the mixing container
,A. Workability
Workability describes how easily mortar can be mixed, placed, and tooled
while still developing the required strength and durability after curing.
4. During demolition of an old masonry wall in a hospital facility, what
safety practice should be performed before removing any materials?
A. Increase the demolition speed
B. Identify hazardous materials and establish proper controls
C. Remove all protective equipment
D. Wet the wall with fuel products
B. Identify hazardous materials and establish proper controls
Healthcare facilities may contain hazardous materials such as asbestos or
lead-containing products. Proper identification and control measures are
required before demolition begins.
5. Which masonry unit is commonly used for fire-rated walls because of
its resistance to high temperatures?
A. Wood block
B. Plastic panel
C. Concrete masonry unit
D. Foam board
C. Concrete masonry unit
, Concrete masonry units provide excellent fire resistance and are commonly
used in fire-rated construction assemblies.
6. When constructing a brick wall, why is it important to stagger vertical
joints between courses?
A. To reduce the amount of mortar used
B. To improve wall strength and distribute loads
C. To make the wall easier to paint
D. To increase brick color variation
B. To improve wall strength and distribute loads
Staggering joints creates a stronger masonry bond by distributing stresses
and preventing continuous weak points through the wall.
7. A mason notices that newly installed mortar joints are drying too
quickly during hot weather. What action should be taken?
A. Add excessive water after installation
B. Protect the masonry and control moisture loss
C. Remove all mortar joints
D. Increase direct sunlight exposure
B. Protect the masonry and control moisture loss
Rapid drying can prevent proper mortar hydration and reduce bond
strength. Protection and controlled curing help maintain masonry
performance.
