Abstract :Many studies on the chemical interaction of clay are carried out by ensuring that the clay samples are completely exposed to the chemical effect. However, the contact of clays with pollutants is a gradual process that takes time, including the infiltration process. For example, with tsunamis, it becomes possible for clay soils, which have been away from the effect of salt water for years, to meet with sea water, although it is marine clay. It becomes possible for additional settlements to occur in structures built on clay soils that interact with sea water.For this reason, it is important to understand well the osmotic compression phenomenon that can be seen in clay soils. Within the scope of the study, osmotic compression that is a special type of time-dependent deformation, which is a behavior specific to clays, is discussed. It has been tried to explain the osmotic compression of clay, which is a comprehensive subject, the water retention mechanisms of the clay, the structure and fabric, the principles of time-dependent deformation behavior, the basic mechanisms of the osmotic effect in clays, the estimation of osmotic compression and the usability of the related theory.
