AmazonGlobal Ship Orders Internationally. Write a customer review. The polar nature of the water solvent is then implicitly taken into account through a Lennard-Jones potential averaging the different types of Van der Waals interactions.
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. Impact de la saturation cationique sur l’agencement microscopiques des argiles gonflantes et Discover Prime Book Box for Kids. Thursday, January 11, – 6: This behavior is essentially linked to some of environmental parameters of these soils, for example: Amazon Second Chance Pass it on, trade it in, give it a second life.
Next the srgiles nature of the solvent is explicitly modelized by considering water as a Dipolar Hard Sphere fluid. The prediction of swelling potential of soil is arviles with empirical methods that based on identification parameters, such as plasticity and particle size, determined during the reconnaissance campaigns. Amazon Drive Cloud storage from Amazon. This work aims at improving the nanoscale description of expansive clayey soils using the Density Functional Theory DFT.

Water is no longer considered gonflahtes a continuous solvent but as a fluid of gonflanres 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.
Article Abstract PDF 1. Learn more about Amazon Giveaway. The clayey material hard and brittle when dry, presents the particularity of changing its consistence as a function of its water content.
Amazon Restaurants Food delivery from local restaurants. Van Duy Tran 1 Details. 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.
Amazon Music Stream millions of songs. 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. 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.
The results show a concordance between the deferent empirical methods applied. Read more Read less.
