Indian geotechnical journalSummary: The engineering performance of geotechnical structures constructed out of soils in terms of properties such as compressibility, time rate of consolidation, permeability and the like depend upon many factors such as soil clay mineralogy, soil type, stress history, placement conditions and the like. During the land reclamation projects, normally, any of the two processes, namely compaction or reconstitution, is followed. Even though the soils subjected to these two processes have the same clay mineralogical composition and same stress history, their engineering performance could be different. The present experimental work deals with a comparative study of the compressibility, consolidation and permeability behavior of compacted soils with those of the same soils reconstituted at about the same stress history as those of compacted soils. It has been brought out that the reconstituted soils have higher compressibility and higher compression indices than compacted soils. It is shown that the coefficient of consolidation and coefficient of permeability behavior of compacted soils and soils reconstituted with almost the same stress history depend upon the clay mineralogical composition of the soils.
