Laboratory tests and large-scale tests for low carbon concrete ACT
ECOCEM AND BOUYGUES CONSTRUCTION
ConstructionandEcocem: a partnership to accelerate the deployment of low-carbon concrete ACT on a large scale
Début 2025, Bouygues Construction et Ecocem ont signéa partnership to scale up ACT, the low carbon technology developed by Ecocem.
Laboratory tests and large-scale tests were conducted by R&D teamsand Innovation of Bouygues Construction and Ecocem to promote the use of ACT on Bouygues yards.
The partnership revolves aroundthree axes to test, evaluate and validate ACT technology :
- A comprehensive testing programwas conducted within the Bouygues Construction's ‘Material Labs' to assess the performance of ACT technology under laboratory conditions.
- Large-scale field operations: des coulages ont été réalisés dans les installations Scale One® de Bouygues Construction à Chilly-Mazarin, en conditions hivernales et estivales afin de mesurer l’impact de la température sur le comportement du béton.
- A life-size model including common structural elements of constructionwas built on Scale One® site under the usual casting conditions. The possibility of building a carbon-reduced concrete structure on scale 1 will make it possible to monitor its evolution over time.
À Haubourdin (59),on a Bouygues building site North East Building, the first concrete sails incorporating ACT technology and produced from a networked concrete plant were successfully sunk.
A synergy between two key players in the sector that contributes to significantly reducing the carbon footprint of construction projects.
