Already Graded A+
Question 1
What is the primary purpose of fire-resistant construction materials?
A. Improve aesthetics
B. Delay fire spread and maintain structural integrity
C. Increase building cost
D. Improve ventilation
Answer: B
Rationale: Fire-resistant materials are designed to slow fire progression and
preserve structural stability.
Question 2
Which material is naturally fire-resistant?
A. Untreated wood
B. Concrete
C. Plastic
D. Foam insulation
,Answer: B
Rationale: Concrete has high thermal mass and resists fire exposure.
Question 3
Steel loses strength at approximately what temperature?
A. 100°C
B. 300°C
C. 500°C
D. 1200°C
Answer: C
Rationale: Structural steel significantly weakens around 500°C.
Question 4
What is gypsum board primarily used for?
A. Waterproofing
B. Fire resistance in walls and ceilings
C. Electrical wiring
D. Roofing insulation only
Answer: B
, Rationale: Gypsum contains water molecules that slow heat transfer.
Question 5
What property makes gypsum fire-resistant?
A. High oil content
B. Water in crystalline structure
C. Metal reinforcement
D. Plastic coating
Answer: B
Rationale: When heated, gypsum releases water vapor that resists heat.
