Influence of Smectite Content on the One-Dimensional Deformation Behavior of Reconstituted High Plasticity Clays

Danish geotechnical engineers are challenged when designing buildings and foundations on terrain-near Danish Palaeogene clays. The Palaeogene clays does not behave as the typical Danish deposits which have been subjected to glaciation events, which is why some of the characteristics of the Palaeogene clays are presented in the present paper. It has been speculated that the behavior to a large degree is due to the high content of the clay mineral smectite in the Palaeogene deposits, which is why a series of test on artificial, reconstituted, preconsolidated clay specimens has been conducted. From this series of tests it is seen that the content of smectite does significantly influence the deformation behavior of clay.
