A masonry wall is specified with Type S mortar but is constructed using Type N mortar instead. What is
the primary concern?
A. Improved flexibility
B. Reduced compressive strength and bond performance
C. Faster construction
D. Reduced cost
Answer: B
Rationale: Type S mortar has higher strength than Type N and is required for structural applications.
2.
A contractor installs vertical reinforcement but fails to maintain proper clear cover. What risk does this
create?
A. Improved bonding
B. Corrosion and reduced durability
C. Faster construction
D. Reduced cost
Answer: B

consequence?
A. Increased strength
B. Reduced load capacity
C. Faster curing
D. Improved bonding
Answer: B
4.
A masonry wall experiences diagonal cracking under load. What is the likely failure mode?
A. Flexural failure
B. Shear failure
C. Compression failure
D. Thermal expansion
Answer: B

5.
A project requires high compressive strength masonry units but lower strength units are used. What is
the impact?
A. Improved flexibility
B. Reduced structural capacity
C. Faster installation
D. Reduced cost
Answer: B
6.
A bond beam is omitted in a reinforced masonry wall design. What is the primary risk?
A. Increased strength
B. Reduced lateral load resistance
C. Faster construction
