At the event on March 23, speakers John Day from Wagners Earth Friendly Concrete, Charles Allen from OTB Concrete Ltd, and Richard Sutherden from J Murphy & Sons Ltd will discuss geopolymer concrete in tunnelling – developments in ultra low-carbon concrete for underground works.
John Day will explain progress made over the last decade in the testing and use of geopolymer concrete and how adoption is increasing worldwide. Charles Allen will discuss applications for geopolymer concrete in tunnel linings and its high durability performance, and Richard Sutherden will set out a case study of use and adoption on LPT2 and how a collaborative approach between client, contractor and designer is essential for future adoption.
Reducing embodied carbon is a must for the future sustainability of infrastructure projects. Shaft and tunnel linings contribute around 70% of embodied carbon associated with a tunnelling project. Geopolymer concrete can reduce the embodied carbon of concrete by up to 80%.
The lecture, which starts at 18:30 (GMT), is an in-person event at the Institution of Civil Engineers, Great George St, London and it will also be live streamed at https://youtu.be/kFi2ggLBHu4
