Question

The liquid limit and plastic limit of sample are 65% and 29% respectively. The percentage of the soil fraction with grain size finer than 0.002 mm is 24. The activity ratio of the soil sample is

Answer 1

Given :-

$\sf\:W_{L}$ = 65 °/°

$\sf\:W_{p}$ = 29 °/°

→$\sf\:I_{p} = W_{L} - W{p}$ = 36°/°

Activity ratio

→$\dfrac{I_{p}}{C}$

$= \: \: \: \frac{36}{24} \\ \\ = 1.5$
