The implemented configuration enables the laboratory to perform :<\/p>\n\n\n\n

    \n
  • three-point and four-point flexural testing ;<\/li>\n\n\n\n
  • deflection measurement using dedicated instrumentation ;<\/li>\n\n\n\n
  • crack mouth opening displacement monitoring during testing ;<\/li>\n\n\n\n
  • test data acquisition and analysis in accordance with laboratory procedures.<\/li>\n<\/ul>\n\n\n\n

    The solution can also accommodate additional fixtures and testing applications to support the laboratory\u2019s future requirements.<\/p>\n\n\n\n

    Eiffage Infrastructure is involved in the construction and maintenance of transport infrastructure, civil engineering structures, roads and urban developments.<\/p>\n

    As part of its material testing and characterisation activities, the laboratory needed to expand its testing capabilities for UHPFRC<\/strong>, an ultra-high-performance fibre-reinforced concrete used in highly stressed structures.<\/p>\n

    Eiffage Infrastructure required equipment capable of testing UHPFRC prism specimens in accordance with EN 14651<\/strong>, including :<\/p>\n

    • three-point and four-point<\/strong> flexural testing ;<\/li>\n
    • deflection<\/strong> measurement ;<\/li>\n

    • reliable data acquisition ;<\/li>\n
    • the ability to integrate additional testing applications over time.<\/li>\n<\/ul>\n

      The objective was to provide a precise, stable and upgradeable testing machine capable of characterising UHPFRC behaviour, particularly after initial cracking.<\/p>\n
