Question
(a) One cubic meter of wet soil weighs 19.8 kN. If the specific gravity of particles is 2.7 and water content is 11%, find the void ratio, dry density and degree of saturation. 10
(b) 25 kg of dry soil was subjected to sieve analysis. The weight of the soil retained in each sieve is as given in the table below. Determine the effective size of the soil. Draw the particle size distribution curve and determine the uniformity coefficient and coefficient of curvature and comment on the result : 10
| Sieve size | Mass of soil retained (kg) |
| :--- | :--- |
| 2 mm | 0 |
| 1 mm | 2.02 |
| 0.6 mm | 3.51 |
| $425\ \mu$ | 7.53 |
| $212\ \mu$ | 8.15 |
| $150\ \mu$ | 2.81 |
| $75\ \mu$ | 0.90 |
| pan | 0.08 |
