Q2. Which mortar type is best suited for load-bearing stone walls?
A) Type O
B) Type N
, C) Type S
D) Type M
Answer: D
Rationale: Type S mortar has high compressive strength, making it suitable for load-bearing
applications, whereas Type O and N are lower-strength mortars.
Q3. What is the minimum compressive strength of Type S mortar?
A) 1,200 psi
B) 1,800 psi
C) 2,500 psi
D) 3,000 psi
Answer: B
Rationale: Type S mortar, commonly specified for structural masonry, has a minimum
compressive strength of 1,800 psi when properly cured.
Q4. Which of the following materials is most commonly used as mortar in masonry work?
A) Pure cement
B) Lime only
C) Portland cement, lime, and sand
D) Epoxy cement
Answer: C
Rationale: Standard masonry mortar consists of Portland cement, hydrated lime, and sand to
