Sep 15, 2018 · Jose et al., 1988, Jose et al., 2000 noted the effects of air/oven drying on the physical properties of Cochin marine clays from around Indian peninsula, which were characterised by high Atterberg limits and natural water contents. They concluded that oven drying reduces the liquid limit by >50%, which is attributed to aggregation of finer particles.

Mar 23, 2017 · A. Atterberg defined the boundaries of four states in terms of "limits". A fine-gained soil can exist in any of several states; which state depends on the amount of water in the soil system. When water is added to a dry soil, each particle is covered with a film of adsorbed water. If the addition of water is continued, the thickness of the water film on a particle increases.
