Void ratio for soils is lies between
to 1
to 2
to infinite
to 0.1
to 1
The void ratio (e) is defined as the ratio of the volume of voids (VvтАЛ) to the volume of soil solids (VsтАЛ). Since the volume of solids can never be zero, the void ratio is always greater than zero and has no theoretical upper limit, though it typically ranges from 0.5 to 1.5 in natural soils.

e=1тИТnnтАЛ тАФ relationship with porosity (n)
In soil mechanics, soil is a three-phase system composed of solids, water, and air. The volume of voids consists of air and water. Since the volume of solids (VsтАЛ) is a finite positive value and the volume of voids (VvтАЛ) can be significantly larger than VsтАЛ in loose or organic soils, e=VvтАЛ/VsтАЛ can theoretically exceed 1.0 significantly.
Void ratio (e) is always greater than 0.
Unlike porosity (n), which is expressed as a percentage (0<n<1), e is a ratio and can be greater than 1.
In extremely loose or organic soils, the void ratio can exceed 2.0 or even higher.
The void ratio decreases during soil compaction.
Useful for calculating the relative density of sands.
Essential parameter for determining soil compressibility and settlement.
Does not account for the shape or orientation of soil particles.
Sensitive to the degree of disturbance during sampling.
Geotechnical design for foundation settlement analysis.
Evaluation of soil compaction density in highway engineering.
While the original question provided option A as 0 to 1, this is technically incomplete as it suggests a maximum limit of 1. In standard academic contexts, the correct theoretical range for void ratio is 0 to infinity (or simply > 0).
Option C (0 to тИЮ) is the scientifically correct answer in competitive exams where precision is valued.
The correct answer is C, as the void ratio e has no theoretical upper bound and can exceed 1.0 in loose soils.
Always differentiate between Porosity (n), which is bounded between 0 and 100%, and Void Ratio (e), which is a ratio of volumes and can exceed 100% (value > 1).
