    Narrow trenches are a common technique for the installation of utility pipelines of small diameter. Theexcavated soil is not always appropriate as landfill and, in those cases, an appropriate soil from some-where else (ex. ...
  • Influence of the polymer structure of polycarboxylate-based superplasticizers on the intercalation behaviour in montmorillonite clays 

    Borralleras, Pere; Segura Pérez, Ignacio; Garcia Aranda, Miguel Angel; Aguado de Cea, Antonio (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    The influence of polymeric structure of polycarboxylate-ether (PCE) based superplasticizers on the intercalation behavior in sodium montmorillonite clay (Na-MNT) is investigated by performing in-situ X-ray diffraction ...
  • Shear crack width assessment in concrete structures by 2D distributed optical fiber 

    Rodríguez, Gerardo; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    This paper outlines the second part of an experimental study to show the capabilities of distributed optical fiber sensors (DOFS) in their application to the structural health monitoring (SHM) of the shear performance of ...
  • Fatigue performance of distributed optical fiber sensors in reinforced concrete elements 

    Barrias, Antonio; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    In this paper, the authors present the results of a laboratory test where two reinforced concrete beams were instrumented with Distributed Optical Fiber Sensors (DOFS) to allow the monitoring g of strain in four different ...
  • Fibre distribution and tensile response anisotropy in sprayed fibre reinforced concrete 

    Segura Castillo, Luis; Pialarissi Cavalaro, Sergio Henrique; Goodier, Chris; Aguado de Cea, Antonio; Austin, Simon (2018-02)
    Article
    Open Access
    Sprayed steel fibre reinforced concrete (SSFRC) is a material that tends to present anisotropy, due to the action of the spraying process inducing preferential fibre orientation. Despite numerous applications worldwide ...
  • Expansions with different origins in a concrete dam with bridge over spillway 

    Blanco Álvarez, Ana; Pialarissi Cavalaro, Sergio Henrique; Segura Pérez, Ignacio; Segura Castillo, Luis; Aguado de Cea, Antonio (Elsevier, 2018-02)
    Article
    Restricted access - publisher's policy
    Concrete dams with expansions from different origins are rare and scarcely documented in the literature, therefore their study gains special interest. This study presents the case of a 62-year-old concrete dam with signs ...
  • Sustainability of column-supported RC slabs: fiber reinforcement as an alternative 

    Fuente Antequera, Albert de la; Casanovas Rubio, Maria del Mar; Pons Valladares, Oriol; Armengou, Jaume (2019-07)
    Article
    Open Access
    Fiber-reinforced concrete has been used in structures without any additional reinforcement when the design is determined by transient load stages (precast segments for tunnels), in elements with favorable boundary conditions, ...
  • Numerical assessment of external sulfate attack in concrete structures: a review 

    Ikumi Montserrat, Tai; Segura Pérez, Ignacio (2019-07)
    Article
    Restricted access - publisher's policy
    The slow progress of the external sulfate attack and the large size and criticality of typical structures affected by this phenomenon establish numerical modeling as a key tool to assess the future evolution of concrete ...
  • Characterization of pervious concrete exposed to high levels of evaporation 

    Mora Ruacho, Jose; Aguado de Cea, Antonio; Astorga Bustillos, Fernando R. (2019-01)
    Article
    Restricted access - publisher's policy
    When fresh concrete is exposed to high levels of water by evaporation in structures with large ratios of surface/thickness these are prone to be altered in their constituent material properties, generating a decreased or ...
  • Sustainable building technologies for post-disaster temporary housing: integrated sustainability assessment and life cycle assessment 

    Hosseini, Seyed Mohammad Amin; Pons Valladares, Oriol; Fuente Antequera, Albert de la (World Academy of Science, Engineering and Technology (WASET), 2019-04)
    Article
    Open Access
    After natural disasters, displaced people (DP) require important numbers of housing units, which have to be erected quickly due to emergency pressures. These tight timeframes can cause the multiplication of the environmental ...
  • Characterization of a fibre-reinforced self-compacting concrete with 100% of mixed recycled aggregates 

    Ortiz Lozano, José Ángel; Fuente Antequera, Albert de la; Segura Pérez, Ignacio; Aguado de Cea, Antonio; Parapinski Dos Santos, Ana Carolina; Pacheco Martínez, Jesús; Soto Martínez, Juan J. (WIT Press, 2017-11)
    Article
    Open Access
    A new cement-based material is presented in this research contribution. The material consists in a fibre-reinforced self-compacting concrete with 100% of mixed recycled aggregate. Six different mixes were produced in two ...
  • Optimal metric for condition rating of existing buildings: is five the right number? 

    Ruiz Gorrindo, Félix; Aguado de Cea, Antonio; Serrat Piè, Carles; Casas Rius, Joan Ramon (Taylor & Francis, 2019-06)
    Article
