Numerical model of free swelling processes in compacted MX-80 bentonites
This work proposes a formulation to simulate the swelling of compacted bentonites, focusing the analysis on the modelling of the increase of macrostructural void ratio generated by the destructuration of the microstructure ...
Temperature effect on gypsum-bearing soil and supported (building) foundations: The case of the Central Storage Facility of Villar de Cañas, Spain
Thermal load imposed on the ground by the foundations of some singular buildings may produce variations in geochemistry conditions. In soils containing soluble salts, such as gypsum, their dissolution/precipitation rates ...
Testing different strategies for the remediation of soils polluted with lindane
This work attempts to clarify the remediation processes involved in the treatment of soil spiked with non-soluble species like lindane. To achieve this goal, the remediation of spiked soil is evaluated coupling electro-kinetic ...
M4EKR, Multiphysics for ElectroKinetic Remediation of Polluted Soils
(EDP Sciences, 2020-10-16)
Electrokinetic soil remediation (EKR) is one of the most promising techniques for decontamination of low permeability soils, in which the most classical techniques have been found to be less efficient. However, its practical ...
Determination of the hygric properties of the heritage stone of the Cathedral of Cuenca through the water absorption by capillarity test
This work analyses the characterization of the hygric behaviour of a stone heritage material by solving the inverse problem using experimental data obtained from a water absorption by capillarity test (EN 15801). This ...
A new double-porosity macroscopic model of bentonite free swelling
A macroscopic model based on a double-porosity approach is proposed to simulate the swelling caused by the subdivision of particles and aggregates that occurs when bentonites are hydrated under a high water content and low ...
Development of a THMC code for bentonites in COMSOL Multiphysics
(EDP Sciences, 2020-10-16)
The proposed use of active clays for the isolation of radioactive wastes in deep geological repositories has been followed by a deeper understanding of this type of soils. This increased knowledge has led to the need for ...
Coupling of chemical and hydromechanical properties in bentonite: A new reactive transport model
The reactive transport framework ORCHESTRA was used to implement a dual porosity reactive transport system that accounts for mechanical processes relevant for confined swelling clays at full saturation. The new implementations ...
