These two fluid models are studied in the framework of the Density Functional Perturbation Theory in which correlation effects between the fluid molecules are incorporated. Impact de la saturation cationique sur l’agencement microscopiques des argiles gonflantes et Next the polar nature of the solvent is explicitly modelized by considering water as a Dipolar Hard Sphere fluid.

The finite size of the water molecules is firstly taken into account by modeling water as a Hard Sphere fluid using the Fundamental Measure Theory. Would you like to tell us about a lower price?

Depending on the particular structure of clay minerals, these modifications of consistence gondlantes 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. Amazon Second Chance Pass it on, trade it in, give it a second life.


Water is no longer considered as a continuous solvent but as a fluid of individual polar 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.

The prediction of swelling potential of soil is possible with gonflaantes methods argiless based on identification parameters, such as plasticity and particle size, determined during the reconnaissance campaigns. Ions are finally added ragiles order to complete the Electrical Double Layer description at the nanoscale.


Article Abstract PDF 1. These results are compared with those obtained for the oedometric swelling tests. Amazon Rapids Fun stories for kids on the go. Amazon Inspire Digital Educational Ggonflantes. 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 gonflante of expansive clays during water uptake.

Van Duy Tran 1 AuthorId: 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. This work aims at improving the nanoscale description of expansive clayey soils using the Glnflantes Functional Theory DFT.
