    Tunnelling under the York University Schulich Building was one of the milestones of the Toronto-York Spadina Subway Extension Project. The challenge was to bore the tunnel under a flagship building only one diameter below ...
  • Practical considerations regarding results from static and dynamic load testing of bridges 

    Olaszek, Piotr; Casas Rius, Joan Ramon (2019-02)
    Article
    Accés obert
    Bridge tests are a helpful tool for bridge assessment and evaluation. Both in the case of a static and dynamic load testing, each element of the test: the load selection and application, the creation of a numerical model ...
  • Lessons learned about the diagnosis of pathologies in concrete dams: 30 years of research and practice

    Article
    Accés restringit per política de l'editorial
    Studies on the diagnosis of pathologies of concrete dams are a valuable reference for professionals managing such assets. However, detailed information is rarely reported in the literature. This paper compiles the most ...
  • Influence of experimental procedure on d-spacing measurement by XRD of montmorillonite clay pastes containing PCE-based superplasticizer 

    Borralleras, Pere; Segura Pérez, Ignacio; Garcia Aranda, Miguel Angel; Aguado de Cea, Antonio (2019-02)
    Article
    Accés restringit per política de l'editorial
    This study investigates the influence of the experimental procedure on determining the d-space enlargement of montmorillonite clay (MNT) produced by the absorption of polycarboxylate (PCE) based superplasticizers. d-Spacing ...
  • The role of porosity in external sulphate attack 

    Ikumi Montserrat, Tai; Pialarissi Cavalaro, Sergio Henrique; Segura Pérez, Ignacio (2019-03)
    Article
    Accés restringit per política de l'editorial
    Design codes promote a limitation of permeability (indirectly of porosity) to reduce the sulphate ingress and improve the resistance of concrete and mortar to external sulphate attack (ESA). However, porosity could also ...
  • Effects of biaxial confinement in mortars exposed to external sulfate attack 

    Ikumi Montserrat, Tai; Segura Pérez, Ignacio; Pialarissi Cavalaro, Sergio Henrique (2019-01)
    Article
    Accés restringit per política de l'editorial
    Research on external sulfate attack (ESA) is usually performed on small scale specimens under free expanding conditions. However, most field structures cannot expand freely due to confinement induced by the ground or other ...
