Best answer
Correct Answer - Option 4 : 12.7 mm, 25

Explanation:

According to standard test method ASTM D-4318, the moisture content (the liquid limit of soil) is determined by Casagrande’s liquid device, at which a groove closure of 12.7 mm occurs at 25 blows.

Liquid limit:

  • Liquid limit is defined as the minimum water content at which soil has a tendency to flow.
  • At liquid limit soil posses from the liquid stage of consistency to the plastic stage of consistency and vice versa.
  • All soils at liquid limit possess the same negligible shear strength of 2.7 kN/m2, which can be just measured.
  • Liquid limit is found out by the following two methods:
    • Cassagrande's apparatus
    • Cone penetration test
