Laboratory tests and large-scale tests for low carbon concrete ACT
ECOCEM AND BOUYGUES CONSTRUCTION
Construction and Ecocem : a partnership to accelerate the deployment of low-carbon concrete ACT on a large scale
In early 2025, Bouygues Construction and Ecocem signed a partnership to scale up ACT, the low carbon technology developed by Ecocem.
Laboratory tests and large-scale tests were conducted by R&D teams and Innovation of Bouygues Construction and Ecocem to promote the use of ACT on Bouygues yards.
The partnership revolves around three axes to test, evaluate and validate ACT technology :
- A comprehensive testing program was conducted within the Bouygues Construction's ‘Material Labs' to assess the performance of ACT technology under laboratory conditions.
- Large-scale field operations : castings were made in the Scale One® facilities of Bouygues Construction in Chilly-Mazarin, in winter and summer conditions to measure the impact of temperature on concrete behaviour.
- A life-size model including common structural elements of construction was 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.
In 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.
