PROBLEM No. 2 The properties of six different clayey soils are shown below based from a series of Atterberg Limit tests and Hydrometer tests. Complete the table by determining the plasticity index, PI, and activity, A of each soil. Also, classify each soil based on the activity, A (inactive, normal, active). Lastly, determine the probable clay mineral composition (Kaolinite, Illite, Montmorillonite) of each soil based on the activity, A.
