engineering recuitment UKPSC AE Civil 2021 Mock Test (Re-Exam) Soil Mechanics and Foundation Engineering Index Properties
The determination of plasticity index and the percentage by weight of clay mineral finer than 2 μ present in the soil were done for two soil samples A and B. The ratio of plasticity index to the percentage of clay size particle for the samples A and B are given in the table.
| Soil Sample | Ratio of plasticity index to percentage of clay size particle |
| Sample A | Less than 0.75 |
| Sample B | Greater than 1.25 |
The two soil samples A and B are classified as:
1
Sample A: Normal; Sample B: Inactive
2
Sample A: Active; Sample B: Normal
3
Sample A: Active; Sample B: Inactive
4
Sample A: Inactive; Sample B: Active
