1. The primary purpose of special inspection for structural masonry is to
verify compliance with:
A. Architectural drawings only
B. Contractor means and methods
C. Approved construction documents and referenced standards
D. Manufacturer installation instructions only
Correct Answer: C
Rationale: Special inspection ensures masonry construction conforms to
approved plans, specifications, and applicable codes and standards.
, 2. Which code is most commonly referenced for masonry construction in
the IBC?
A. ACI 318
B. TMS 402/602
C. AISC 360
D. ASCE 7
Correct Answer: B
Rationale: TMS 402 (design) and TMS 602 (specifications) govern masonry
construction referenced by the IBC.
3. The minimum compressive strength of masonry, f′m, is determined by:
A. Prism testing only
B. Unit strength method only
C. Either prism testing or unit strength method
D. Mortar cube testing
Correct Answer: C
Rationale: Codes permit determining f′m using either prism tests or the
unit strength method.
4. Which mortar type typically has the highest compressive strength?
A. Type O
B. Type N
, C. Type S
D. Type M
Correct Answer: D
Rationale: Type M mortar has the highest cement content and compressive
strength.
5. The inspector must verify that reinforcing steel is free of:
A. Mill scale
B. Surface rust
C. Oil, grease, and deleterious materials
D. Minor bends
Correct Answer: C
Rationale: Reinforcement must be clean to ensure proper bond with grout
and masonry.
6. Minimum lap splice length for reinforcing steel in masonry is based on:
A. Bar diameter only
B. Masonry unit size
C. Bar size, grade, and masonry strength
D. Wall height
, Correct Answer: C
Rationale: Lap splice requirements depend on reinforcement properties
and masonry strength.
7. Grout used in masonry must have a minimum slump of:
A. 4 inches
B. 6 inches
C. 8 inches
D. 12 inches
Correct Answer: C
Rationale: TMS 602 requires grout slump between 8 and 11 inches for
proper consolidation.
8. When is low-lift grouting typically used?
A. Walls over 12 feet high
B. Walls up to 5 feet before grouting
C. Only for reinforced bond beams
D. For cavity walls only
Correct Answer: B
Rationale: Low-lift grouting limits grout pours to short wall heights for
consolidation control.
