What does the presence of expansive clay indicate for construction?
A. High bearing capacity
B. Risk of shrink-swell behavior
C. Excellent drainage
D. High permeability
Answer: Option B
Solution (By Examveda Team)
Expansive clay swells when wet and shrinks when dry, causing ground movement.This shrink-swell behavior can damage foundations and pavements.This Question Belongs to Geological Engineering >> Engineering Geology For Construction
