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.
