Question: Laboratory tests on a soil obtained from foundation site having mass sieved 200g.
0

cumulative mass retained on 4.75 mm sieve = 30g,

cumulative mass retained on 75 $\mu$ sieve = 150g

$D_{10} = 0.07, D_{30} = 0.12mm, D_{60} = 1.95 mm, W_l = 38%, W_P = 28%$

Classify the soil as per is classification system.

cumulative mass retained on 75 $\mu$ sieve = 150g

% retained on 75 $\mu$ = $\frac{150}{2009} = 74%$

% passing 75 $\mu$ sieve > 50% => fine grained soil,

$I_P = W_L - W_P = 38 - 28 = 10$

From plasticity chart, $I_P = 10, W_L=38$

Indicate that soil lies in second zone($W_L = 35 - 50$) and below A line so soil is M1 or 0I.
