Renewal of reinforced concrete bridges by means of UHPFRC – Experiences from 400+ applications. Ultra-High-Performance Fiber-Reinforced Cementitious composite UHPFRC is a novel building material that is characterized by high mechanical strength and durability. UHPFRC is used in Switzerland for 20 years to rehabilitate and strengthen existing reinforced concrete bridges. This article first appraises more than 400 UHPFRC applications. The findings from numerous applications when casting UHPFRC on bridge deck slabs are prepared in such a way that they can be adopted ready for use by the interested reader. Finally, a recently completed example of a 65-year-old reinforced concrete bridge strengthened with UHPFRC shows how the basic concepts and the great potential of the UHPFRC technology can be transferred into practice, while preserving resources and building culture values.
