10. A fine grained soil has a liquid limit of 200% and a plastic limit of 45%. The natural water content of the sol in the field is 60% and the clay content is 63%. Calculate the plasticity index, liquidity index and the soil activity. From this, what is the soil state in the field? From the liquid limit, what is a logical assumption regarding the predominant mineral in the soil?
