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

These results are compared with those obtained for the oedometric swelling tests. Amazon Inspire Digital Educational Resources. Explore the Home Gift Guide. A certain percentage of moisture may transformed it into a plastic and manageable material. This work aims at improving the nanoscale description of expansive clayey soils using the Density Functional Theory DFT.

Tuesday, December 12, – ComiXology Thousands of Digital Comics. Next the polar nature of the solvent is explicitly modelized by considering water as a Dipolar Hard Sphere fluid. Swelling clay Porous media Electrical double layer Discontinuous solvent Disjoining pressure Interparticle correlations. Ions are finally added in order to complete the Electrical Double Layer description at the nanoscale.

The prediction of swelling potential of soil is possible with empirical methods that based on identification parameters, such as plasticity and particle size, determined during the reconnaissance campaigns.

Amazon Restaurants Food delivery from local restaurants. Water is no longer considered as a continuous solvent but gonlfantes 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.

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.
