Civil Engineering MCQs

Civil Engineering MCQs cover structural analysis, concrete technology, geotechnical, transportation, fluid mechanics, materials, and surveying, helping PPSC, FPSC, NTS candidates and graduates strengthen theory, apply concepts, and excel in engineering exams, interviews, and professional assessments.

Q: The term β€œcamber” in road construction refers to
A) Pavement strength
B) Thickness of layer
C) Crown slope
D) Load distribution
βœ… Correct Answer: C
Explanation: Camber is the slope provided to drain off rainwater from the road surface.
Q: Tensile cracks in concrete generally appear at
A) Corners
B) Along beams
C) Mid-span
D) Supports
βœ… Correct Answer: C
Explanation: Flexural tension at mid-span leads to cracking if reinforcement is insufficient.
Q: Under earthquake loads, ductility in structures is essential for
A) Speed
B) Energy dissipation
C) Durability
D) Strength
βœ… Correct Answer: B
Explanation: Ductility allows structures to absorb and dissipate seismic energy without sudden failure.
Q: The main cause of efflorescence on brick walls
A) Salt content
B) High temperature
C) Acid rain
D) Dust particles
βœ… Correct Answer: A
Explanation: Water-soluble salts migrate to the surface and crystallize, forming efflorescence.
Q: The moisture content in a fully saturated soil sample is called
A) Saturation moisture content
B) Optimum content
C) Natural moisture
D) Liquid limit
βœ… Correct Answer: A
