A concrete answer for circular construction: three prototypes reusing saw-cut elements
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer
Existing concrete buildings should be retained for as long as possible to reduce the environmental burden of demolition and new construction. However, when urban pressure makes demolition unavoidable, salvaging and reusing concrete elements elsewhere in ne ...
2024Rhodanie urbaine
Sergi Aguacil Moreno, Martine Laprise, Judith Elisa Drouilles, Pascal Pierre Michon, Clément Cattin, Sara Sonia Formery Regazzoni
Regeneration of urban areas from neighborhoods in transition to innovative components Research at the LAST aims to contribute to transitions towards sustainability in the built environment by integrating environmental, socio-cultural, and economic paramete ...
2023Low-tech methods for the reuse of reinforced concrete structural elements
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Nicole Widmer, Julie Rachel Devènes
Most of existing buildings are made of concrete, new buildings are being built with it and others are demolished when still in good structural condition. This drives increased demands for raw materials, greenhouse gas emissions, and an accumulation of demo ...
2023Reusability Assessment of Obsolete Reinforced Concrete Structural Components
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Julie Rachel Devènes
The production of concrete, the most widely used construction material, detrimentally affects the environment. Obsolete reinforced concrete (RC) load-bearing structures, even when still in good condition, are today prematurely crushed and landfilled or rec ...
Springer2023Does carbon footprint reduction impair mechanical properties and service life of concrete?
Karen Scrivener, Diana Londoño Zuluaga
The aim of this study is to evaluate how much the changes in the concrete mix design, which enable carbon footprint reduction, are impacting mechanical properties and predicted service life of concrete structure. The starting point of this study was concre ...
SPRINGER2023Concrete: Cosmetic and Care
Sarah Nichols, Akshar Shaileshkumar Gajjar, Marion Moutal
‘Concrete: Cosmetic and Care’ focuses on a heavy heritage: the mass of mainly post-war structures in reinforced concrete. The post-war building boom covered the globe with an unprecedented amount of concrete. Production of every ton of cement alone release ...
2023Reuse of concrete components in new construction projects: Critical review of 77 circular precedents
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer
Extracting pieces of concrete from obsolete buildings and reusing them, as is, in new assemblies is today rarely considered a strategy for improving the sustainability of the construction sector. By delaying the crushing of concrete into aggregates and avo ...
2023A Simple, Closed-Form Method for Determining the Superelevation of Tall Reinforced Concrete Buildings
David Michael Volpe Ruggiero, Paola Costanza Miglietta
The vertical shortening of tall buildings is not negligible, and it is important to account for these deformations to minimize differential movement and ensure that the finished building is level. Compensation via superelevation is common in reinforced con ...
Springer2023From concrete waste to walls An investigation of reclamation and digital technologies for new load-bearing structures
Corentin Jean Dominique Fivet, Stefana Parascho, Maxence Grangeot
Our research explores opportunities in using unaltered concrete rubbles from demolition for the digital construction of structural walls. Through research by iterative making, we identify relevant upcycling processes and design strategies and explore new t ...
2023From concrete waste to walls An investigation of reclamation and digital technologies for new load-bearing structures
Corentin Jean Dominique Fivet, Stefana Parascho, Maxence Grangeot
The research presented in this paper highlights current practices for the end-of-life of concrete and explores opportunities in using unaltered concrete rubbles from demolition for the digital construction of structural walls. Through research by iterative ...
