Ultra High Performance Fiber Concretes (UHPC) are cementitious matrix materials, reinforced with fibres and offering compressive strengths of between 150 and 250 MPa. Advances in the field of admixtures, formulation methods and the use of ultrafine have led to a revolution of concretes. The range has expanded: from standard concretes with compressive strengths of 30 mpa to high performance concretes (bhp: more than 50 mpa) and very high performance (bthp: more than 80 mpa).

by Shih Ho Chao. Abstract. An original concept is presented for the durable rehabilitation and strengthening of concrete structures. The main idea is to use ultra-high performance fibre reinforced concrete (UHPFRC) complemented with steel reinforcing bars to protect and strengthen those zones of the structure that are exposed to severe environmental influences and high mechanical loading. To evaluate the vulnerability of ultra-high performance fibre-reinforced concrete (UHPFRC) infrastructure to rigid projectile penetration, over the last few years CEA-Gramat has led an experimental and numerical research programme in collaboration with French universities. emergence of Ultra-High Performance Fibre Rein-forced Concrete (UHPFRCs ) characterize by a d very low water/binder ratio and high fibre content.
