Q: Pick up the correct statement from the following.
  • A. The maximum size of a coarse aggregate is 75 mm and minimum is 4.75 mm
  • B. The maximum size of the fine aggregate is 4.75 mm and minimum 0.75 mm
  • C. The material having particles of size varying from 0.06 mm to 0.002 mm is known as silt
  • D. All options are correct
Correct Answer: Option D - Coarse aggregate size > 4.75 mms • Fine aggregate size < 4.75 mm • Silt size 0.002 mm to 0.075 mm • Clay size < 0.002 mm • Sand size 0.075 mm to 4.75 mm
D. Coarse aggregate size > 4.75 mms • Fine aggregate size < 4.75 mm • Silt size 0.002 mm to 0.075 mm • Clay size < 0.002 mm • Sand size 0.075 mm to 4.75 mm

Explanations:

Coarse aggregate size > 4.75 mms • Fine aggregate size < 4.75 mm • Silt size 0.002 mm to 0.075 mm • Clay size < 0.002 mm • Sand size 0.075 mm to 4.75 mm
