Comportement au jeune âge et différé d'un BFUP écrouissant sous les effets thermomécaniques

This thesis is dedicated to study the early age behavior and time dependant as well as the thermo-mechanical response under restraint of a hardening Ultra High Performance Fiber Reinforced Concrete (UHPFRC). The knowledge of the UHPFRC behavior is indispen ...

Mechanical behaviour of Ultra High Performance Fibre Reinforced Concretes (UHPFRC) at early age, and under restraint

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

At early age, ultra high performance fibre reinforced concretes (UHPFRC)undergo significant volumes changes (thermal deformation and autogenous shrinkage)related to their composition. These deformations can be restrained by different elements respective to ...

Thermo-mechanical response of UHPFRC at early age — Experimental study and numerical simulation

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen, Hamid Sadouki

The thermal effects on the Ultra High Performance Fiber Reinforced Concrete (UHPFRC) behavior are still not completely known. Under high temperatures, the processes that interact at early age are thermo-activated. All the experimental results obtained with ...

Thermo mechanical effects in Ultra-High Performance Fibre Reinforced Concretes (UHPFRC) at early age

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen, Hamid Sadouki

The extremely low permeability of Ultra-High Performance Fibre Reinforced Concretes (UHPFRC)associated to their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjected t ...

UHPFRC early age time dependent response - experimental characterization and numerical analysis

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

Thin ultra high performance fibre reinforced concretes overlays are suitable for rehabilitation of structures thanks to their enhanced properties. However, in such composite structures, restrained differential shrinkage cracking is an important concern. To ...

Evaluation of UHPFRC activation energy using empirical models

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen, Hamid Sadouki

The influence of thermal curing on the evolution of the material properties and the UHPFRC behaviour was investigated. Tests results showed a beneficial effect of a high temperature curing on the early age material properties due to the thermo-activation e ...

UHPFRC tensile creep at early age

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen, Hamid Sadouki

Ultra high performance fibre reinforced concrete (UHPFRC) early age viscoelastic behaviour under tension was investigated. The tests results showed a high creep potential due to the high volume paste (88%). This result is of major importance because the vi ...
