It was found that to speak of shrinkage means that one must define the initial soil volume and occurring changes. Three definitions of soil volume were determined, based on settlement, horizontal & vertical shrinkage and soil matrix only. For the first two definitions, a decrease in minimal void ratio was found, indicating impact of applied pressure. The impact was quantified using a mathematical formulation based on incremental stress and a compression constant. For the last definition, no impact was detected, indicating that shrinkage is a characteristic material relationship on soil matrix level.
