ITAtech launch ‘low carbon linings’ Activity Group

The ITA Group, ITAtech is going to launch a new Activity Group on low carbon concrete linings for shafts and tunnels.

Concrete is recognized as the second most widely consumed commodity on the planet after water. It also contributes approximately 8% of global carbon emissions; the main source of these emissions is the manufacture of Ordinary Portland Cement (CEM I)

In a tunnelling project, it is generally considered that 60% to 70% of embodied carbon is contained in the concrete linings of the shafts and tunnels. It is paramount, therefore that the tunnelling industry does its utmost to significantly reduce or eliminate its use of cement in all applications – segmental linings, in-situ linings, sprayed concrete, and annulus grouts.

There is a great challenge for the coming years to develop a solution for low carbon lining and an opportunity for ITAtech to provide a guideline/recommendation for the market.

If you wish to join this activity group, do not hesitate to contact the ITAtech secretariat: secretariat-itatech@ita-aites.org
