  • 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 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
    Restricted access - publisher's policy
    In the context of the built environment in the recent years, the concept of maintenance has changed from corrective to preventive maintenance. There is evidence that preventive maintenance is much more efficient than ...

  • Case study of failure of long prestressed precast concrete girder during lifting 

    Fuente Antequera, Albert de la; Bairán García, Jesús Miguel; Pialarissi Cavalaro, Sergio Henrique (Elsevier, 2019-06)
    Article
    Restricted access - publisher's policy
    Improvements in concrete technology, reinforcing systems and manufacturing enable the use of longer reinforced precast concrete girders, contributing to the competitiveness of this solution for bridge decks. The weight of ...

  • Distributed optical fibre sensors in concrete structures: performance of bonding adhesives and influence of spatial resolution 

    Barrias, Antonio Jose de Sousa; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (Wiley, 2019-03)
    Article

    In this paper, the authors conducted an experiment where a reinforced concrete beam was instrumented with a 5-m long polyimide single distributed optical fibre sensors (DOFS) performing four equal segments externally bonded ...

  • State-of-research on performance indicators for bridge quality control and management 

    Faleschini, Flora; Zanini, Mariano Angelo; Casas Rius, Joan Ramon (2019-03)
    Article
    Open Access
    The present study provides a review of the most diffused technical and non-technical performance indicators adopted worldwide by infrastructure owners. This work, developed within the European COST Action TU 1406—“Quality ...

  • SHM of reinforced concrete elements by Rayleigh backscattering DOFS 

    Barrias, Antonio Jose de Sousa; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (2019-03)
    Article
    Open Access
    This document showcases the latest research conducted within UPC–BarcelonaTech on the performance of distributed optical fiber sensors (DOFS), more specifically the case of the optical backscattered reflectometry (OBR) ...

  • Inlfuence [sic] of early sulfate exposure on the pore network development of mortars 

    Ikumi Montserrat, Tai; Segura Pérez, Ignacio; Pialarissi Cavalaro, Sergio Henrique (Elsevier, 2017-07)
    Article
    Open Access
    The objective of this paper is to evaluate the influence of sulfate exposure on the pore network development of several Portland cement matrices. MIP, XRD and SEM analysis were performed at different ages in samples exposed ...
