The concrete has a carbon footprint that equates to a 62% reduction in CO2e per cubic metre of concrete compared to standard CEM I concrete (according to BSI PAS2050 calculations), yet meeting the same specification in the same raw materials.
The material has been used on a slab and a wall of a building in the site compound of HS2 contractor Align in Hertfordshire. This building houses the pre-casting of bridge sections for the Colne Valley Viaduct….
Robert Gossling, head of commercial engineering solutions at Tarmac, said: “Against the backdrop of the climate emergency, this project underlines the clear benefits which can be unlocked when clients and contractors collaborate, in this case engaging to help understand and accelerate the adoption of this new low carbon concrete solution.
“Together we’ve shown the material is fit for purpose in slabs and walls, with good repeatability and works with standard production and construction methods. This product is a great step along the UK concrete and cement industry’s net zero routemap, and the demonstration will help accelerate adoption of this new concrete….”
