      Article
      Open Access
      Low density composites of sodium montmorillonite and poly(amide-imide) polymers have been created using an ice templating method, which serves as an alternative to the often-difficult foaming of high temperature/high ...

    • Residual strength of compacted boom clay: dependency on stress, suction and microstucture 

      Pérez Canals, Michelle C. (Universitat Politècnica de Catalunya, 2013-10-22)
      Master thesis
      Open Access
      Esta investigación propone estudiar el comportamiento en corte de Boom Clay en estado no saturado desde un punto de vista microestructural. El estudio se centra en muestras compactadas estáticamente para simular el estado ...

    • Secondary compression of clays as a local dehydration process 

      Navarro, Vicente; Alonso Pérez de Agreda, Eduardo (Institution of Civil Engineers (http://www.ice.org.uk/), 2001)
      Article
      Open Access
      Long-term volumetric deformations of clays are interpreted in terms of water transfer from clay aggregates to the bulk water. Chemical potentials for the two states of water are first derived and then integrated into balance ...

    • Self-sealing of boom clay after gas transport 

      González Blanco, Laura; Romero Morales, Enrique Edgar; Levasseur, Severine (Springer, 2023-01-01)
      Article
      Open Access
      In the geological disposal of high-level radioactive waste in argillaceous rocks, studying the barrier integrity after gas transport and the pathway closure thanks to self-sealing capacity is a crucial aspect for the safety ...

    • Single and hybrid organoclay-filled PLA nanocomposites: mechanical properties, viscoelastic behavior and fracture toughening mechanism 

      Lopes Alves, Jefferson; De Tarso Viera e Rosa, Paulo; Redondo Realinho, Vera Cristina de; Antunes, Marcelo de Sousa Pais; Velasco Perero, José Ignacio; Morales, Ana Rita (Wiley, 2021-04-04)
      Article
      Open Access
      Poly (lactic acid) (PLA) nanocomposites based on single and hybrid organic-modified montmorillonites were previously studied in terms of their morphologi-cal, thermal and fire performance. As surfactants of the organoclays ...

    • Suction-controlled experiments on Boom clay 

      Bernier, F.; Volckaert, G.; Alonso Pérez de Agreda, Eduardo; Villar, M. (Elsevier, 1997)
      Article
      Open Access
      The understanding of the thermo-hydro-mechanical behaviour of a clay barrier is needed for the prediction of its final in situ properties after the hydration and thermal transient in a radioactive waste repository. As ...

    • Sulfate performance of blended cements (limestone and illite calcined clay) exposed to aggressive environment after casting 

      Rossetti, Agustín; Ikumi Montserrat, Tai; Segura Pérez, Ignacio; Irassar, Egardo Fabián (2021-09-01)
      Article
      Open Access
      This paper evaluates how early aggressive exposure affects the sulfate resistance of blended cements containing limestone filler and/or calcined clay. Mortar and cement paste specimens were elaborated with different ...

    • Sulfate resistance of blended cements (limestone illite calcined clay) exposed without previous curing 

      Rosetti, Agustín; Ikumi Montserrat, Tai; Segura Pérez, Ignacio; Irassar, Egardo Fabián (2020)
      Conference report
      Open Access
      Durability in aggressive environments is an important factor to extend the service life of concrete and the use ternary blended cements (limestone filler + calcined clays) can contribute to this purpose. In sulfate ...

    • The influence of ambient conditions into rammed earth compressive strength
