Q55
According to Atterberg, the soil is said to be of medium plasticity if the plasticity index PI is
A.
0 < PI < 7
B.
7< PI < 17
AnswerC.
17 < PI < 27
D.
PI > 27
Answer: Option B
Solution
Answer: Option B
Solution:
According to Atterberg, the soil is said to be of medium plasticity if the plasticity index (PI) is7 < PI < 17.The plasticity index (PI) is a measure of the plasticity of a soil and is calculated as the difference between the liquid limit (LL) and the plastic limit (PL).
Soils with a PI between 7 and 17 are considered to have medium plasticity. This range indicates moderate changes in consistency with changes in moisture content.
Therefore, the correct option is 7 < PI < 17.
