Abstract: Ultra-high-performance fiber-reinforced concretes (UHPFRC) are the outcome of a quest that began in the 1930s to find means of increasing the mechanical strength of concrete, in particular its compressive strength.
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). In particular, ultra-high-performance fiber-reinforced concrete (UHPFRC), which was developed in the mid-1990s, is very sensitive to these factors due to its extremely high compressive strength (in excess of 150 MPa) and flowable characteristics with high volume fractions of steel fibers (more than 2% by volume) , . To achieve such a high strength material, a low water-to-binder ratio (W/B) (normally W/B = 0.2) is applied with ultra-fine admixtures and heat treatment at 90 °C. In this study the efficiency of the use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) for the strengthening of existing Reinforced Concrete (RC) beams has been investigated.

The tensile stress–strain characteristics
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. Ultra‐high performance concrete with a compressive strength of more than 140 N/mm2 reacts very brittle without the addition of fibres.

At designing economical and resource‐efficient building components as well as performance‐optimized materials, the supporting effects of the additional microfibres must be considered. Ultra-high-performance fibre reinforced concrete (UHPFRC) exhibits remarkable compressive strength and ductility which, when applied to structural members, enable significant reduction of the cross-section.
