1. Which of the following is NOT a type of bond used in brickwork?
A. English bond
B. Flemish bond
C. Herringbone bond
D. Spiral bond
Answer: D) Spiral bond
Rationale: The most common types of brick bonds include English bond, Flemish bond, and
Herringbone bond. Spiral bond is not a recognized brick bonding pattern.
2. Which type of concrete is used for underwater construction?
A. Ordinary Portland Cement
B. Air-entrained concrete
C. Rapid hardening concrete
D. Waterproof concrete
Answer: D) Waterproof concrete
Rationale: Waterproof concrete is used in underwater construction because it resists water
penetration and can withstand the challenging conditions of underwater environments.
3. What does the term 'curing' in concrete work refer to?
,A. The process of mixing concrete
B. The process of maintaining moisture and temperature to allow hydration
C. The process of applying finish to concrete
D. The process of cutting concrete
Answer: B) The process of maintaining moisture and temperature to allow hydration
Rationale: Curing ensures that concrete has enough moisture to fully hydrate, leading to
maximum strength and durability.
4. Which material is commonly used for making a damp-proof course (DPC)?
A. Concrete
B. Asphalt
C. Glass
D. Aluminum
Answer: B) Asphalt
Rationale: Asphalt is commonly used for DPC because it is water-resistant and prevents moisture
from rising through walls. It is often used as a waterproofing material in construction.
5. Which of the following is the most common type of brick used in construction?
A. Fly ash brick
B. Clay brick
C. Concrete brick
, D. Calcium silicate brick
Answer: B) Clay brick
Rationale: Clay bricks are the most commonly used type of bricks in construction due to their
availability, cost-effectiveness, and strength. They have been used for centuries.
6. What is the typical span of a concrete slab without intermediate supports?
A. 3–5 meters
B. 5–7 meters
C. 7–9 meters
D. 10–12 meters
Answer: A) 3–5 meters
Rationale: A typical concrete slab can span between 3 to 5 meters without intermediate supports,
depending on the design and load. Longer spans require additional reinforcement or support.
7. In a reinforced concrete beam, the part that resists compression is called the:
A. Web
B. Flange
C. Reinforcement
D. Slab
Answer: B) Flange
A. English bond
B. Flemish bond
C. Herringbone bond
D. Spiral bond
Answer: D) Spiral bond
Rationale: The most common types of brick bonds include English bond, Flemish bond, and
Herringbone bond. Spiral bond is not a recognized brick bonding pattern.
