    • 2D reactive transport modeling of the interaction between a marl and a CO2-rich sulfate solution under supercritical CO2 conditions 

      Dávila Ordóñez, Maria Gabriela; Luquot, Linda; Soler Matamala, Josep M.; Cama Robert, Jordi; Luquot, Linda (John Gale, 2016-11-01)
      Article
      Open Access
      The circulation of CO2-rich solutions through fractured marl cores (caprock) under different flow rates and supercritical CO2 conditions (PTotal = 150 bar, pCO2 = 61 bar and T = 60 °C) led to mineral changes caused mainly ...
    • Efficiency of magnesium hydroxide as engineering seal in the geological sequestration of CO2 

      Dávila Ordóñez, Maria Gabriela; Cama Robert, Jordi; Galí i Medina, Salvador; Luquot, Linda; Soler Matamala, Josep M. (John Gale, 2016-05)
      Article
      Open Access
      Injection of CO2 at depth will cause the acidification of groundwater. As a preliminary study for the potential use of MgO as an alternative to Portland cement in injection wells, MgO carbonation has been studied by means ...

      Article
      Open Access
      A laboratory-scale tracer test has been carried out to improve the characterization of the transport properties of the concrete from the radioactive waste disposal facility at El Cabril (Spain). High entry pressure was ...
    • 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
      Open Access
      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
