Mathematics · Soil Mechanics
A sieve analysis test is conducted on a soil sample having D10 = 0.115 mm, D30 = 0.53 mm, and D60 = 1.55 mm. The values of the coefficient of uniformity (Cu) and coefficient of curvature (Cc) are respectively:
- 1Cu = 18.47 and Cc = 3.57
- 2Cu = 10.47 and Cc = 5.57
- 3Cu = 15.47 and Cc = 4.57
- 4Cu = 13.48 and Cc = 1.58✓
Correct answer
Cu = 13.48 and Cc = 1.58
