Zero carbon timber concrete composites

Decarbonised concrete in use.

Timber concrete composite being craned

Following on from proof-of-concept timber concrete composites manufactured at BE-ST for a live build at Laing O’ Rourke, Laing O’ Rourke are now looking to decarbonise the concrete used in this system and in all of their projects. The system will use cem-free concrete and cement replacements (geopolymers) and is looking to replace as much concrete with timber as possible and support Scottish mass timber initiative.


Workshops are taking place to scope out:

  • Benefits of each type of mass timber for TCCs
  • Shear connections 
  • Membrane
  • Cost and availability
  • Fire performance

The product will then be manufactured with potential to decarbonise concrete across other projects.
