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 ...

Le 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 ...

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 ...

Composite 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 ...

Contribution 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 ...
