Attempt in App

Answer 1

Explanation

It is defined as the ratio of unconfined compressive strength (UCS) of an undisturbed soil sample to that of the remoulded sample at the same water content.
It indicates the loss in strength due to disturbance or remoulding of soil.

Additional Information

Activity:

Defined as the ratio of plasticity index to the percentage of clay fraction (<2 micron size).
Indicates the expansive nature of clay soils.

Damping:

Refers to the energy dissipation property of soil during cyclic or dynamic loading.
Commonly discussed in earthquake and vibration analysis, not related to strength comparison.

Plasticity:

Refers to the ability of soil to undergo deformation without cracking or crumbling.
Measured using Atterberg limits: Liquid limit, Plastic limit, and Plasticity Index.
