Question

In a shrinkage limit test, the volume and mass of a dry soil pit are found to be 50$c{m}^3$ and 88 g respectively. The specific gravity of the soil solids is 2.71 and the density of water is 1 g/cc. The shrinkage limit (in % up to two decimal places) is

• A. 19.91

Answer 1

The correct option is A 19.91


$V_s=\frac{88}{G_s\times {\gamma }_w}=\frac{88}{2.71\times 1}=32.47$

$w_s=\frac{(50-32.47)\times 1}{88}=0.1991=19.91\%$
