Question

The weight and volume of a fully saturated soil sample are 55.4 gm and 29.2 cc respectively. after drying in an oven for 24 hours, its weight and volume reduces to 39.8 gm and 21.1 cc respectively. the shrinkage limit of the soil is

Answer 1

the shrinkage limit of the soil is 18.8%. in this question they directly give all things hence it is simple.

Answer 2

Hey dear,

# Shrinkage limit -
- It is the water content where further loss of moisture will not result in any more volume reduction.

● Answer -
Shrinkage limit for soil = 18.8 %.

● Explanation -
# Given -
W1 = 55.4 gm
W2 = 39.8 gm
V1 = 29.2 cc
V2 = 21.1 cc

# Solution -
Shrinkage limit of soil is calculated by formula -
G = W2 / (V1γ-W1+W2)
G = 39.8 / (29.2×1-55.4+39.8)
G = 18.8 %

Therefore, shrinkage limit for soil is 18.8 %.


Hope this helped...
