Ifsttar is to develop new types of concrete for the two tunnels on the railway being built between Lyon, France, and Turin in Italy. Called the Lyon-Turin Ferroviaire, the Ambin Tunnel will be 57km and the Orsiera Tunnel 19km. Ifsttar joined forces with Holcim, Vicat, the materials research lab LERM, and the railway designer to find ways of using a third of the estimated 19million m³ of debris removed while digging the tunnels.

Ifsttar joined forces with 680 Holcim, 684 Vicat, the materials research lab LERM, and the railway designer to find ways of using a third of the estimated 19million m³ of debris removed while digging the tunnels.

It will be turned into aggregates to make concrete for the tunnels.

Studies will be done on the nature of sulphates to avoid deterioration.
