Environmental and economic analysis of new construction techniques reusing existing concrete elements: two case studies
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Julie Rachel Devènes
As the most widely used construction material worldwide, concrete is the main cause of greenhouse gas emissions, material depletion, and waste generation by the construction industry. Typically, concrete waste is crushed and, at best, reclaimed into recycl ...
2022Re:Crete – reuse of concrete elements in new structures: A footbridge prototype
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Jan Friedrich Georg Brütting, Julie Rachel Devènes
Concrete accounts for the largest share of worldwide building material use and waste generation, with cement production being responsible for approximately 9% of global anthropogenic CO2 emissions. A currently untapped strategy to significantly reduce thes ...
CRC Press2022Le béton de réemploi, ressource territoriale à mobiliser
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer
Plus que de tout autre matériau, le bâti suisse est fait de béton. Matériau aux nombreuses qualités, il est présent dans toute nouvelle construction, souvent en grande quantité. Malgré cela, des tonnes de béton sont quotidiennement démolies, pour des raiso ...
2022RE:CRETE - Building out of concrete, without pouring concrete (video)
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Maxence Grangeot, Jan Friedrich Georg Brütting, Julie Rachel Devènes
Concrete is the most ubiquitous construction material worldwide but also a major source of waste and CO2 emissions. Worse, it is too often crushed down prematurely for recycling or filling. Can’t we do better? We seek to reuse concrete from demolition site ...
EPFL2021Composite model for predicting the punching resistance of R-UHPFRC-RC composite slabs
Eugen Brühwiler, Maléna Bastien Masse
Adding a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over a Reinforced Concrete (RC) slab is an efficient reinforcement method for existing structures. The thin layer of UHPFRC serves ...
Elsevier2016Contribution of R-UHPFRC Strengthening Layers to the Shear Resistance of RC Elements
Eugen Brühwiler, Maléna Bastien Masse
To strengthen a reinforced concrete (RC) slab with deficient shear resistance, it is proposed to add to the top of the slab a 25-50 mm thick layer of ultra-high performance fibre reinforced cement-based composite (UHPFRC) with small diameter rebars (R-UHPF ...
Iabse2016Experimental investigation on punching resistance of R-UHPFRC–RC composite slabs
Eugen Brühwiler, Maléna Bastien Masse
An effective method to strengthen existing Reinforced Concrete (RC) structures is to add a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over the concrete slab to create a composite ele ...
Springer Verlag2016Effect of fiber orientation on the in-plane tensile response of UHPFRC reinforcement layers
Eugen Brühwiler, Emmanuel Denarié, Maléna Bastien Masse
The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...
Elsevier2016Structural Behavior of R-UHPFRC - RC Composite Slabs
The application on existing Reinforced Concrete (RC) slabs of cast-on-site Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC) layers is an efficient reinforcement technique, currently spreading. The thin layer of UHPFRC, with or withou ...
EPFL2015Strengthening the Chillon viaducts deck slabs with reinforced UHPFRC
Eugen Brühwiler, Maléna Bastien Masse
Located in Switzerland, Chillon viaducts are two parallel highway posttensioned concrete bridges built in the late 1960s. The concrete of the deck slabs of these bridges shows signs of early stages of the alkali-aggregate reaction (AAR), which will induce, ...
