Abstract: Ultra-high Performance Fibre-Reinforced Concrete (UHPFRC) has emerged as a fruitful
result of research efforts based on three main ideas: strength and compactness improvement
of cement materials by intense reduction of the water to binder ratio; efficient use of fibers to
provide post-cracking tensile capacity and pseudo-ductility; and reduction of natural
imperfections due to aggregate in limiting their size and selecting very high quality materials
in an optimized grading. From twenty years, UHPFRC has demonstrated outstanding strength
and resistance to transfer, so that durability and lightness of prestressed members have been
mostly searched in structural applications. Later on, UHPFRC has been adopted to develop
attractive façade and roofing components, owing to renewed aesthetic possibilities associated
to durable mineral surface quality, lightness, semi-transparency and possible complex shapes.
Based on this experience the standardization process launched in France has resulted in
three complementary standards, addressing UHPFRC structural design, material production
and control (both documents published in 2016), and execution of structures (to be published
by end 2018). Further expected development (deserving significant educational efforts)
especially concern civil engineering facilities answering high durability and sustainability
demands, light and efficient solutions for protection and structural repair, and architectural
achievements in façades and public buildings.
