masonry construction in the United States?
A. ACI 318
B. TMS 402/602
C. ASTM C150
D. IBC Chapter 16
Rationale: Structural masonry design and construction are
primarily governed by The Masonry Society standards (TMS

Correct Answer: B
2. The primary purpose of grout in masonry construction is to:
A. Increase color consistency
B. Reduce thermal expansion
C. Bond masonry units and reinforce steel

masonry special inspector?
A. Designing masonry walls
B. Approving structural calculations
C. Verifying materials and installation compliance
D. Hiring subcontractors
Rationale: Special inspectors verify compliance with approved
plans and codes, not design or contracting.

specified for structural CMU units?
A. 500 psi
B. 1000 psi
C. 1900 psi
D. 3000 psi
Rationale: Structural CMUs typically meet ASTM requirements
around 1900 psi minimum strength.

8. What is the primary function of mortar in masonry
construction?
A. Structural reinforcement
B. Thermal insulation
C. Unit bonding and leveling
D. Waterproofing system
Rationale: Mortar bonds masonry units and provides leveling,
not primary structural capacity.
Correct Answer: C
9. Cold joints in masonry are typically caused by:
A. Excess reinforcement
B. Interruptions in grout placement
C. High cement content
D. Excess curing time
Rationale: Cold joints form when grout or mortar placement is
interrupted.
Correct Answer: B
