  • Reactive transport modelling of a high-pH infiltration test in concrete 

    Chaparro Sánchez, Maria Carme; Soler Matamala, Josep M.; Saaltink, Maarten Willem; Mäder, URS (2017-06)
    Article
    Restricted access - publisher's policy
    A laboratory-scale tracer test was carried out to characterize the transport properties of concrete from the Radioactive Waste Disposal Facility at El Cabril (Spain). A hyperalkaline solution (K-Ca-OH, pH = 13.2) was ...
  • Reactive transport modelling of cement-groundwater-rock interaction at the Grimsel Test Site 

    Chaparro Sánchez, Maria Carme; Saaltink, Maarten Willem; Soler Matamala, Josep M. (2017-06)
    Article
    Restricted access - publisher's policy
    An in situ experiment at the Grimsel Test Site (Switzerland) to study water-cement-rock interaction in fractured granite was modelled. It consisted of a hardened cement source in a borehole intersecting a water conducting ...
  • Salinity is reduced below the evaporation front during soil salinization 

    Gran Esforzado, Meritxell; Carrera Ramírez, Jesús; Olivella Pastallé, Sebastià; Massana, Jordi; Saaltink, Maarten Willem; Ayora Ibáñez, Carlos; Lloret Morancho, Antonio (2009-11-01)
    Conference report
    Open Access
    La salinización de suelos es un problema global. Generalmente, la salinización es causada por el transporte de sales hacia la superficie por capilaridad y, a pesar de su importancia global, los mecanismos que la controlan ...
  • Simulation of chemical reaction localization using a multi-porosity reactive transport approach 

    Soler Sagarra, Joaquim; Luquot, Linda; Martínez Pérez, Laura; Saaltink, Maarten Willem; Gaspari, Francesca de; Carrera Ramírez, Jesús (John Gale, 2016-05)
    Article
    Open Access
    Results of reactive transport laboratory experiments often suggest that pore scale heterogeneity induces localization of reactions (the generation of local micro environments favoring reactions that would not occur in a ...
  • Taller de pràctiques de laboratori d'hidrologia subterrània mitjançant models físics experimentals 

    Fernández García, Daniel; Sánchez Vila, Francisco Javier; Saaltink, Maarten Willem; Custodio Gimena, Emilio (Universitat Politècnica de Catalunya. Institut de Ciències de l'Educació, 2013-02-08)
    Conference lecture / Conference report
    Open Access
    En cap de les assignatures de grau d'hidrologia subterrània s'imparteixen pràctiques de laboratori. Això fa que l'estudiant rebi una educació purament teórica sense aaribar a assolir correctament els conceptes bàsics ...
  • Temperature driven vapor fluxes in soils cause a net recharge 

    Gran Esforzado, Meritxell; Saaltink, Maarten Willem; Dandar, Enkhbayar; Carrera Ramírez, Jesús (2017)
    Conference lecture
    Open Access
    Temperature gradients can drive vapor diffusion by controlling vapor pressure in the soil. We studied vapor diffusion for soils in two different climates: A semiarid climate at El Cabril (Córdoba, Spain) and a subarctic ...
  • Use of redundant data to reduce estimation errors in geochemical speciation 

    Gaspari, Francesca de; Saaltink, Maarten Willem; Carrera Ramírez, Jesús; Slooten, Luit Jan (2015-04)
    Article
    Open Access
    Speciation is the process of evaluating the concentrations of all the species in a chemical system from equilibrium conditions and measured data such as total concentrations of components, electrical conductivity, pH, redox ...
  • Water, vapour and heat transport in concrete cells for storing radioactive waste 

    Chaparro Sánchez, Maria Carme; Saaltink, Maarten Willem (Elsevier, 2016-08)
    Article
    Open Access
    Water is collected from a drain situated at the centre of a concrete cell that stores radioactive waste at ‘El Cabril’, which is the low and intermediate level radioactive waste disposal facility of Spain. This indicates ...
