1. During inspection of reinforced concrete masonry, which condition most
directly affects the ability of grout to fully consolidate around reinforcing
steel?
A. The nominal color of the masonry units
B. Excessive mortar squeeze-out at the bed joint
C. Obstructions, excessive congestion, or inadequate cleanout access within the
grout space
D. The type of weather-resistant coating on the wall
Answer: Obstructions, excessive congestion, or inadequate cleanout access
within the grout space
Rationale: Grout must flow and consolidate throughout the reinforced cell.
Congested reinforcement, mortar fins, debris, and inadequate cleanouts can
,prevent complete encapsulation and create voids that compromise structural
performance.
2. A masonry wall is specified with Type S mortar. Which property is most
important when verifying that the field-mixed mortar is appropriate for the
specified application?
A. Its color matches the approved sample
B. Its ingredients and proportions comply with the specified mortar type and
applicable requirements
C. Its slump is identical to concrete slump
D. Its compressive strength exceeds concrete strength
Answer: Its ingredients and proportions comply with the specified mortar type
and applicable requirements
Rationale: Mortar classification is based on prescribed proportions and
performance requirements. The inspector should verify materials, batching,
mixing, and documentation rather than judge compliance solely by appearance.
3. A special inspector observes that reinforcement is placed directly against
the face shell of a concrete masonry unit. What is the primary concern?
A. Excessive wall color variation
B. Increased mortar bond
C. Insufficient grout and masonry cover around the reinforcement
D. Excessive mortar strength
Answer: Insufficient grout and masonry cover around the reinforcement
Rationale: Reinforcement must be positioned so that the required grout space
and cover can be achieved. Steel placed against masonry faces can prevent
adequate encapsulation and may violate detailing requirements.
4. What is the principal inspection concern when masonry units are delivered
to the project with significant variations in dimensions?
,A. The units will necessarily have excessive compressive strength
B. Dimensional variation may affect coursing, joint thickness, alignment, and
structural detailing
C. The mortar will automatically become weaker
D. Reinforcement will automatically corrode
Answer: Dimensional variation may affect coursing, joint thickness, alignment,
and structural detailing
Rationale: Unit dimensions directly influence bed and head joints, coursing,
tolerances, openings, reinforcement placement, and wall geometry. Significant
variation should be evaluated against the applicable unit specification and
project requirements.
5. What is the purpose of a masonry prism test?
A. To determine the color of masonry units
B. To measure mortar flow only
C. To evaluate the compressive strength of masonry as an assembled system
D. To determine reinforcing-bar yield strength
Answer: To evaluate the compressive strength of masonry as an assembled
system
Rationale: A masonry prism incorporates masonry units and mortar, and when
applicable grout, to provide a representation of assembled masonry behavior
rather than testing individual components independently.
6. A masonry wall contains vertical reinforcement and grout. The inspector
discovers that mortar droppings have accumulated in the reinforced cells
before grouting. What should the inspector do?
A. Ignore the condition because grout will dissolve the mortar
B. Add water to the cell
C. Require correction or cleaning in accordance with the approved construction
requirements before grouting
D. Increase grout strength without cleaning
, Answer: Require correction or cleaning in accordance with the approved
construction requirements before grouting
Rationale: Mortar droppings can obstruct grout flow and create ungrouted
voids. Cells and cleanouts must be sufficiently clear for proper grout placement
and consolidation.
7. Which masonry component normally provides the primary bond between
adjacent masonry units in conventional mortar-jointed construction?
A. Reinforcing steel
B. Grout alone
C. Mortar joints
D. Flashing alone
Answer: Mortar joints
Rationale: Mortar provides the bedding and bonding medium between masonry
units. Reinforcement and grout perform additional structural functions but do
not replace the mortar joint system.
8. What is the inspector's primary responsibility when reviewing shop
drawings for reinforced masonry?
A. Redesign the wall
B. Select the contractor's preferred materials
C. Verify that construction is consistent with approved documents and identify
discrepancies for resolution
D. Approve substitutions without design-professional authorization
Answer: Verify that construction is consistent with approved documents and
identify discrepancies for resolution
Rationale: The special inspector observes and reports compliance. Design
responsibility generally remains with the registered design professional, not the
special inspector.
