Liquid limit

Plastic limit

Natural water content

42

20

30

56

34

50

Which of the clays, X or Y, experiences larger settlement under identical loads; is more plastic; and is softer in consistency?

 

A.
X, Y and X
B.
Y, X and X
C.
Y, X and Y
D.
X, X and Y
Answer ( Option C)

Y, X and Y

Solution

Clay X Clay Y

WL = 42

WP = 20

WN = 30

WL = 56

WP = 34

       WN = 50
Plasticity index,
Clay X Ip = WL — Wp = 42 — 20 = 22
Clay Y Ip = 56 — 34 = 22
Settlement of clay layer
Coefficient of copression,
CC = 0.009 (WL — 10)
CC α WL
Hence
• Clay Y will experience larger settlement.
• Ip is same in both the samples, wL of clay Y is more so it's dry strength will be less and plasticity is a measure of dry strength hence plasticity of Y will be less. Thus, plasticity of sample X will be more.
Ic of Y is less so Y is softer in consistency.
