Using Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) to improve durability is a promising option seen the extraordi-nary performance of this material when applied in a composite section

This paper proposes a method for predicting the flexural response of ultra-high-performance fibre-reinforced concrete (UHPFRC) beams, including an experimental test framework and associated numerical analyses. The experimental programme includes compressive and tensile tests at the material level and a beam test at the structural level.

Abstract. Ultra-high performance fibre reinforced concrete (UHPFRC) has very high compressive strength up to 200 MPa and exhibits strain hardening effects under flexural loading. The bond strength between UHPFRC and steel reinforcement is much better than the normal strength concrete.

Ultra high performance fibre concrete. 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. In this paper an investigation is made of the applicability of the ASTM C 1609 procedure for testing toughness of ultra high performance fibre reinforced concretes containing a large amount of fibre (≥2% by volume) and exhibiting deflection hardening behaviour. 2009-10-06 · Brühwiler E, Denarié E (2008) Rehabilitation of concrete structures using ultra high performance fibre reinforced concrete.
