**Sample CE8491 Question Paper Soil Mechanics:**

5. The mass of wet soil when compacted in a mould was 19.55 kN. The water content of the soil

was 16%. If the volume of the mould was 0.95 m3. Determine (i) dry unit weight, (ii) Void ratio,

(iii) degree of saturation and (iv) percent air voids. Take G = 2.68. (AUC May/June 2012) CE8491 Question Paper Soil Mechanics

6. In a hydrometer analysis, the corrected hydrometer reading in a 1000 ml uniform soil

suspension at the start of sedimentation was 28. After a lapse of 30 minutes, the corrected CE8491 Question Paper Soil Mechanics

hydrometer reading was 12 and the corresponding effective depth 10.5 cm. the specific gravity

of the solids was 2.68. Assuming the viscosity and unit weight of water at the temperature of the

test as 0.001 Ns/m2 and 9.81 kN/m3 respectively. Determine the weight of solids mixed in the CE8491 Question Paper Soil Mechanics

suspension, the effective diameter corresponding to the 30 minutes reading and the percentage

of particle finer than this size. (AUC May/June 2012)

7. An earthen embankment of 106 m3 volume is to be constructed with a soil having a void ratio of

0.80 after compaction. There are three borrow pits marked A, B and C having soils with voids CE8491 Question Paper Soil Mechanics

ratios of 0.90, 0.50 and 1.80 respectively. The cost of excavation and transporting the soil is Rs 0.25, Rs 0.23 and Rs 0.18 per m3 respectively. Calculate the volume of soil to be excavated

from each pit.Which borrow pit is the most economical? (Take G = 2.65). (AUC Nov/Dec 2011) CE8491 Question Paper Soil Mechanics

8. A laboratory compaction test on soil having specific gravity equal to 2.67 gave a maximum dry

unit weight of 17.8 kN/m3 and a water content of 15%. Determine the degree of saturation, air

content and percentage air voids at the maximum dry unit weight.What would be theoretical

maximum dry unit weight corresponding to zero air voids at the optimum water content?
