Problem-2
Test conducted on a soil sample gave the following results:
Number of blows
10
19
23
27
40
Water content (%)
60.0
45.2
39.8
36.5
25.2
Two determinations for the plastic limit gave water contents of 20.3% and 20.8%.
Determine
(a) the liquid limit and plastic limit,
(b) the plasticity index,
(c) the liquidity index if the natural water content is 27.4%, and
(d) the void ratio at the liquid limit if Gs=2.7.
(e) If the soil were to be loaded to failure, would you expect a brittle failure?
