An oedometer test is conducted for a soil sample. The sample is consolidated under vertical stress of 50 kPa. The oedometer test finished at 144 min and data are given in table I. The average thickness of the sample is 20 mm. Predict the coefficient of consolidation (cv, in mm^2/min) using Casagrande log t method and Taylor square root of t method. Please use the empty graphical papers.
As a result of sieve analysis and hydrometer analysis on a soil sample, gravel 40% and sand 18%. Liquid limit value of the soil 58% and plasticity index was determined as 32%. D60, D30 and D10 values according to grain distribution curve 2.4mm, 0.9mm and 0.2mm respectively. According to the findings obtained, the soil sample Make USCS classification.

Discuss your results and compare your results with any published data. For the bulk density test, obtain the value of dry density. How does the values of (i) void ratio (ii) porosity influenced your results? How will these values differ if the soil is fully saturated, partially saturated or submerged? Support your assertions using relevant phase relationship equations. Whatwill happen to the values of particle density (specific gravity) obtained if the soil sample contain large quantities of peat or organic material? How will the results be used in specific practical conditions in the construction industry? Explain any source(s) of error in your experiment and state how it affected your result.
