    A diffusion-reaction model for the carbonation process of oilwell cement exposed to carbonated brine under CO2 geological storage conditions is presented. The formulation consists of two main diffusion/reaction field ...
  • Modelling tritium transport, matrix diffusion and multiphase flow in a concrete cell used for storing radioactive waste at El Cabril (Spain) 

    Chaparro Sánchez, Maria Carme; Saaltink, Maarten Willem (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Comunicación de congreso

    ‘El Cabril’ is the low and intermediate level radioactive waste disposal facility of Spain. Water with high concentration of tritium is collected from a drain, which is situated at the centre of a concrete cell that stores ...
  • A new re-usable shallow foundation for light loads: load tests and analysis 

    Tarragó, Dani; Gens Solé, Antonio; Rosas, Juan José (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Texto en actas de congreso
    Acceso abierto
    An innovative re-usable shallow foundation system for light loads has been developed consisting of a concrete block and four steel tubes driven into the ground at different orientations. The interaction between the block, ...
  • Backanalysis of preloading 

    Santos Rodríguez, Cristian de; Ledesma Villalba, Alberto; Gens Solé, Antonio (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Texto en actas de congreso
    Acceso abierto
    The paper presents the application of a backanalysis methodology to the inverse analysis of preloading soft clays. The methodology is based on an appropriate selection of the objective function and it uses a novel adaptive ...
  • Hydromechanical modelling of a tunnel excavated in argillaceous rock
