Tensile viscous response of Strain Hardening UHPFRC under high restraint and isothermal conditions

Emmanuel Denarié, Mohamed Abdul Hafiz

Strain Hardening Ultra High Performance Fiber Reinforced Concretes (SH-UHPFRC) have a high elastic limit (around 10 MPa) and high tensile strength (upto 20 MPa) and exhibit significant strain hardening (1 to 4 %) under tensile loads. These appealing featur ...

Validation of a FEA model of structural response of RC-cantilever beams strengthened with a (R-) UHPFRC layer

Eugen Brühwiler, Emmanuel Denarié, Hamid Sadouki

This paper focuses on modelling of structural response of RC cantilever beams retrofitted with a thin layer of Ultra High Performance Fibre Reinforced cement-based Composite (UHPFRC). The complex cracking phenomenon of the resulting RC-UHPFRC composite sys ...

Specification and site control of the permeability of the cover concrete: the Swiss approach

Emmanuel Denarié

It is recognized that most damage to reinforced concrete structures is caused by insufficient durability rather than by low strength. In most cases, the quality and thickness of the cover concrete (covercrete) determine the service life of the structure. S ...

Strain-hardening Ultra-high Performance Fibre Reinforced Concrete: Deformability versus Strength Optimization

Eugen Brühwiler, Emmanuel Denarié

High Performance Cement-based composites such as some UHPFRC or SHCC exhibit a tensile strain hardening response associated to the progressive formation of finely distributed microcracks. Strain Hardening (SH) - UHPFRC with suitable fibrous mixes have a de ...
