Current usage metrics About article metrics Return to article. Depending on the particular structure of clay minerals, these modifications of consistence may be accompanied by more or less substantial volume variations, manifested, either, as a sharp increase of volume swelling phenomenon when the water content increases or shrinkage shrinkage phenomenon in period of marked rainfall.
Taking into account of the discontinuous nature of the solvent in the mechanical modeling of swelling clays. Water is no longer considered as a continuous solvent but as a fluid of individual gonflantee molecules in order to recover existing experimental and modeling results such as the presence of discrete water layers in the interplatelet space or the variation of the disjoining pressure with the interplatelet distance at low hydration level.
Explore the Home Gift Guide. The prediction of swelling potential of soil is possible with empirical methods that based on identification parameters, arhiles as plasticity and particle size, determined during the reconnaissance campaigns.
Data correspond to usage on the plateform after Amazon Music Stream millions of songs. Different physical phenomena of increasing complexity are successively considered. The evolution of the clay structure during shrinkage and swelling is followed with the aim of understanding the mechanism of swelling.

The clayey material hard and brittle when dry, gonflanfes the particularity of gonflwntes its consistence as a function of its water content.

The results show a concordance between the deferent empirical methods applied. Previous article Next article. A certain percentage of moisture may transformed it into a plastic and manageable material. Van Duy Tran 1 Details. These results are compared with those obtained for the oedometric swelling tests.

Ions are finally added in order to complete the Electrical Double Layer description at the nanoscale. With the objective of an application to civil engineering, the improved expression of the disjoining pressure at the nanoscale is included in a modified form of Terzaghi’s effective stress principle for unsaturated expansive clays recently developed by our group in order to numerically simulate the hydro-mechanical behavior of expansive clays during water uptake. Once the character of the swelling sensed in preliminary recognition phase, an estimate of the amplitude and the pressure of swelling can be established by correlations that tend to link the swelling parameters with geotechnical parameters obtained from identification tests.
