      Martínez Estévez, Ariadna (Universitat Politècnica de Catalunya, 2016-05-27)
      Master thesis
      Open Access
      L’emmagatzemen de diòxid de carboni en medis geològics topa entre d’altres amb la preocupació per la generació de vies d’escap cap a l’atmosfera durant l’etapa de desenvolupament dels pous i producció d’aquest . Aquestes ...
    • Avoiding fracture instability in wedge splitting tests by means of numerical simulations 

      Liaudat, Joaquín; Garolera Vinent, Daniel; Martínez Estévez, Ariadna; Carol, Ignacio; Lakshmikantha, Ramasesha Mookanahallipatna; Alvarellos Iglesias, José (2017)
      Conference report
      Open Access
      In this paper, unstable fracture propagation obtained in a in-house performed experimentalWedge Splitting Test (WST) is simulated by means of the FEM and fracture- based zero-thickness interface elements. In order to obtain ...
    • Diffusion-reaction modelling of the degradation of oil-well cement exposed to carbonated brine 

      Martínez Estévez, Ariadna; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (2017)
      Conference report
      Open Access
      The essential aspects of a diffusion-reaction model in development for the degradation process of oil-well cement exposed to carbonated brine are presented in this paper. The formulation consists of two main diffusion/reaction ...
    • Estudio experimental de la expansiones por reacción álcali-sílice a nivel de la interfase pasta de cemento-agregado 

      Martínez Estévez, Ariadna (Universitat Politècnica de Catalunya, 2014-06)
      Master thesis (pre-Bologna period)

    • Modelling acid attack of oilwell cement exposed to carbonated brine 

      Liaudat, Joaquín; Martínez Estévez, Ariadna; López Garello, Carlos María; Carol, Ignacio (John Gale, 2018-01)
      Article
      Open Access
      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 ...
    • Numerical modelling of ASR expansions in concrete 

      Liaudat, Joaquín; Martínez Estévez, Ariadna; López Garello, Carlos María; Carol, Ignacio (American Society of Civil Engineers (ASCE), 2015)
      Conference report
      Restricted access - publisher's policy
      In the context of a project to characterize and model the Alkali-Silica Reaction in concrete, the results of a series of tests on specimens with a single interface between aggregate and cement paste, and the comparison to ...
    • Zero-thickness interface model with chemical degradation by acid attack 

      Martínez Estévez, Ariadna; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (2019)
      Conference report
      Open Access
      Carbon dioxide (CO2) storage in abandoned oil/gas reservoirs is considered a viable alternative to reduce greenhouse gas emissions to the atmosphere. An important element of the risk associated with long-term CO2 storage ...
