Rehabilitation and strengthening of concrete structures using Ultra-High Performance Fibre Reinforced Concrete

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 “harden” and strengthen ...

Fatigue behaviour of bridge deck slab elements strengthened with reinforced UHPFRC

Eugen Brühwiler, Tohru Makita

With the occurrence of higher and more frequent axle loads on roads, in particular bridge deck slabs are more severely solicitated by fatigue loading. To avoid heavy interventions for strengthening of bridge deck slabs, an improved building material is use ...

Cementitious matrices for high performance fibre reinforced cement composites (HPFRCC), in particular ultra-high performance fibre reinforced concretes (UHPFRC)

Emmanuel Denarié, Yves Houst

A cementitious matrix for Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) containing the following constituents (in % mass of dry mix): a) 25 to 65 % Portland cement type CEM I; b) 25 to 70 % of Limestone filler; c) 5 to 15 % ultrafine mineral ad ...

Behaviour of UHPFRC-RC composite beams subjected to combined bending and shear

Eugen Brühwiler, Talayeh Noshiravani

An emerging technique for strengthening of reinforced concrete (RC) slabs is to add a layer of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) with steel rebars as an external tensile flexural reinforcement. This paper presents the results of an ...

Thin UHPFRC slabs without conventional reinforcement as light-weight structural elements

Aurelio Muttoni, Dario Redaelli, Ana Spasojevic

Ultra-High Performance Fibre-Reinforced Concrete (UHPFRC) is a material characterised by significantly improved mechanical and durability properties compared to other concretes. In recent years, an important research effort has been made to identify approp ...

Trwalsze obiekty mostowe dzięki połączeniu UHPFRC i betonu (Towards more efficient structures with composite UHPFRC-concrete construction)

Emmanuel Denarié

The premature deterioration of reinforced concrete road structures is a heavy burden for society. In order to manage structures effectively and to reduce this burden to the minimum, the number and extent of interventions have to be kept to the lowest possi ...

Rehabilitation of concrete structures using Ultra-High Performance Fibre Reinforced Concrete

Eugen Brühwiler, Emmanuel Denarié

An original concept is presented for the rehabilitation of concrete structures. The main idea is to use Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) to “harden” those zones where the structure is exposed to severe environmental and high mechan ...

Influence of tensile properties of UHPFRC on size effect in bending

Aurelio Muttoni, Miguel Fernández Ruiz, Dario Redaelli, Ana Spasojevic

Bending behaviour of members without ordinary reinforcement made of quasi-brittle materials (such as concrete or fibre-reinforced concrete) is subjected to size effect both in terms of strength and ductility. For a typical ultra-high performance fibre-rein ...

Physico-mechanical properties of Ultra High Performance Fibre Reinforced Concrete

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

The effect of different curing temperatures (from 20 to 40 °C) on the compressive strength and hydration of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) have been investigated between 3 and 28 days, using the loss on ignition test (LOI) and th ...

SAMARIS D25b - Guidance for the use of UHPFRC for rehabilitation of concrete highway structures

Emmanuel Denarié

order to manage structures effectively and to reduce this burden to the minimum, the number and extent of interventions have to be kept to the lowest possible level. The extremely low permeability of Ultra-High Performance Fibre Reinforced Concretes (UHPFR ...
