The liquid limit and plastic limit of the soil is 55% and 25% respectively. If the natural water content of the soil is 30%. The correct statement is
  • a)
    Soil is in plastic stage of consistency with consistency index equal to 0.167
  • b)
    Soil is in plastic stage of consistency with liquidity index equal to 0.833.
  • c)
    Soil is in plastic stage of consistency with consistency index equal to 0.833
  • d)
    Soil is in liquid stage of consistency with ratio of consistency index to liquidity index equals to 1.
Correct answer is option 'C'. Can you explain this answer?

Consistency Index (IC) of the soil is:
IP = WL – WP
Wn = 30%
WL = 55%
WP = 25%
Liquidity Index (IL) will be:
Wn = 30%
WP = 25%
WL = 55%
As the soil is in Plastic stage of consistency because both liquidity index and consistency index lies in between 0 to 1.

Explanation:

Liquid Limit:
- It is the water content at which soil changes from plastic state to liquid state.
- Given, Liquid Limit (LL) = 55%

Plastic Limit:
- It is the water content at which soil changes from plastic state to semi-solid state.
- Given, Plastic Limit (PL) = 25%

Natural Water Content:
- It is the water content present in the soil in its natural state.
- Given, Natural Water Content (w) = 30%

Consistency Index and Liquidity Index:
- Consistency Index (Ic) and Liquidity Index (Il) are used to classify the soil into various consistency states.
- Consistency Index (Ic) = (w - PL) / (LL - PL)
- Liquidity Index (Il) = (w - LL) / (LL - PL)

Calculation:
- Consistency Index (Ic) = (30 - 25) / (55 - 25) = 0.167
- Liquidity Index (Il) = (30 - 55) / (55 - 25) = -0.833

As per the given options, the correct statement is option 'C':
- Soil is in plastic stage of consistency with consistency index equal to 0.833
- This means that the soil is in a plastic state, which is between the liquid state and semi-solid state.
- The consistency index value of 0.833 indicates that the soil has a high plasticity and can be easily molded into different shapes.
- The negative value of liquidity index confirms that the soil is in a plastic state and not in a liquid state.

Hence, the correct answer is option 'C'.
