PROBLEM 6: A shrinkage limit test on a clay soil gave the following data: wt. of shrinkage dish &| 38.78 g saturated soil cake wt. of shrinkage dish & 30.46 g oven dry soil cake 10.65 g 16.29 cm wt. of shrinkage dish vol. of shrinkage dish total vol. of oven dry 10.0 cm soil cake solid Compute the shrinkage limit. Hint: Assume that the total volume of the dry soil cake is equal to the total volume at shrinkage limit. a. 15.4% C. 11.2 % ³ b. 10.2% d. 12.7%

A natural soil deposit is to be used for a geotechnical engineering project. Laboratory test results indicate that the soil possesses liquid and plastic limits of LL = 30% and PL = 22%, respectively. In addition, the sieve analysis has produced the following information: • % Passing Sieve No. 4 (4.75 mm) % Passing Sieve No. 200 (75 μm) • Coefficient of Uniformity C₁ 100% 8% 1.590 0.012 Coefficient of Curvature Co (a) Determine the soil's classification in accordance with the Unified Soil Classification System (USCS). (b) To further improve the soil's shear strength performance, the natural soil deposit (possessing an in- situ water content of w = 14%) was compacted in-situ and has achieved a saturation degree of S = 85%. If the specific gravity of soil solids is G, = 2.6, determine the soil's dry and bulk unit weights (ya and y) in its current compacted state.

Someone can help me with this one please.   Following are the results of a shrinkage limit test:

A liquid limit test on a clay was performed with the following results. The natural water content of the clay is 38% and plastic limit is 21%.   Number of Blows 6 12 20 28 32 Water content (%) 52.5 47.1 42.3 38.6 37.5   What is the plasticity index of this clay? (Use Interpolation) Group of answer choices 15.74% 18.99% 18.85% 17.63%   Please answer this asap for upvote. thanks
