Effects of swelly pressure on changes in pore space morphology in Miocene clays from Warsaw: preliminary results and open questions

Ireneusz Gawriuczenkow

Abstract


Miocene clays of the Poznań series from Warsaw were analysed by scanning electron microscope. The influence of swelly pressure causes soil porosity to decrease slightly together with a reorientation of pores. They become more anisometric, while their original matrix microstructure acquires properties of matrix-turbulent microstructure.
