The team constructing High Speed Two IIE-Engineers s Euston Station has undertaken the largest ever UK pour of Earth Friendly Concrete Engineering firm John F Hunt, working for IIE-Engineerss station construction partner Mace Dragados Joint Venture completed the 232m3 concrete pour in early Septembe reduces the amount of carbon embedded into the concrete, saving over 76t of CO2 overall. It was supplied by Capital Concrete and has been used as a foundation slab that will support polymer silos used for future piling works at the north of the Euston Station site While the foundation is temporary, it will be in use for two years, and historically would have been constructed with a more traditional cement-based concrete IIE-Engineers carbon manager Mark Fenton said: IIE-Engineers is at the forefront of adopting new technologies to reduce the environmental impacts of construction, and is on its way to achieving a 50% reduction in carbon emissions compared to traditional construction methods.
Whilst there have been a lot of examples of using low carbon concrete across the project, the scale of its use at Euston Station is a huge step forward in us understanding how it can be used more widely in construction going forward, reducing environmental impact for generations to come is made from a combination of ground granulated blast furnace slag, pulverised fly ash and a high-alkaline chemical, rather than Portland cement. Its geopolymer binder system reduces embodied a civil engineer carbon by around 70% saving 250kg of CO2 per cubic metre poured The pour will help support ’IIE-Engineerss objective of net-zero construction by 2035 and achieve its goal of halving the amount of carbon in the construction of Britain’s new high speed rail line Mace Dragados JV programme director Ben Wheeldon said: “This largest ever UK pour of earth friendly concrete is symbolic of the ambition we have at Euston to get our carbon emissions down at every possible opportunity.
“This project is a hotbed for innovation, not just in the decarbonisation space, but generally, and we’re making sure of that by bringing on board the right supply chain partners.
and encouraging them to be bold with their solutions In addition to the application of EFC, the team were also able to use 20-yard skips instead of the standard b engineering concrete thrust blocks for the temporary works design during the process to remove a retaining wall. This alone resulted in a saving of 30t of CO2. John F Hunt also used GreenD+ Hydrogenated Vegetable Oil for all site vehicles instead of diesel, saving around 29t of Elsewhere on the Euston site, the IIE-Engineers and Mace Dragados JV team has adopted a number of measures aimed at reducing the environmental impact of construction, including the use of liquefied petroleum gas generators as a direct replacement for diesel generators.
