Geotechnical behaviour of low-permeability soils in surfactant-enhanced electrokinetic remediation
(Taylor & Francis, 2015-10)
Electrokinetic processes provide the basis of a range of very interesting techniques for the remediation of polluted soils. These techniques consist of the application of a current field in the soil that develops different ...
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
(Elsevier, 2020-12-03)
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 ...
Scale-up on electrokinetic remediation: Engineering and technological parameters
(Elsevier, 2016-09-05)
This study analyses the effect of the scale-up of electrokinetic remediation (EKR) processes in natural soils. A procedure is proposed to prepare soils based on a compacting process to obtaining soils with similar moisture ...
A new double-porosity macroscopic model of bentonite free swelling
(Elsevier, 2022-08)
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
(Elsevier, 2021-11)
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 ...
Molecular dynamics data for modelling the microstructural behaviour of compacted sodium bentonites
(Elsevier, 2020-11-19)
The water retention curve deduced with low water content data allows the modelling of the bentonite void ratio associated with the pores located inside the clay aggregates, or micropores. However, if both the water content ...
Are electrochemical fences effective in the retention of pollution?
(Elsevier, 2018-08)
In this work, a three-month test is used to evaluate the role of electrokinetic fences in the prevention of the diffusion of herbicide in case of accidental spills of large amounts of highly concentrated products in clay ...
Swelling and mechanical erosion of MX-80 bentonite
(2016-03)
An approach is proposed for simulating the coupled processes of swelling and mechanical erosion of compacted MX-80 bentonites. The loss of mass at the water?soil interface is described by means of a simplified erosion ...
