Joint Technical Event - Geopolymer Concrete in Tunnelling and other applications: Developments in ultra-low carbon concrete

Venue: IStructE, 47-58 Bastwick Street, London, EC1V3PS

Hosted by the London & Southeast Region Concrete Society and the British Tunnelling Society this is a joint event with the central topic of the presentation being ‘Geopolymer Concrete in Tunnelling and other applications: Developments in ultra-low carbon concrete’.

Embodied Carbon reduction is essential for the future sustainability of infrastructure projects. Shaft and tunnel linings contribute in the region of 70% of embodied carbon associated with a tunnelling project. Geopolymer concrete is able to reduce the embodied carbon of concrete by up to 80%.

In this presentation, Charles Allen will explain developments made over the last decade in the testing and use of geopolymer concrete and how adoption is increasing worldwide. He’ll then talk about applications for geopolymer concrete including tunnel linings and its high durability performance.

Finally, Richard Sutherden will set out a case study of testing and use on London Power Tunnels Phase 2 for National Grid and how a collaborative approach between Client, Contractor, and Designer is essential for future adoption and culminated in the World’s largest cement free concrete pour to date.

Speakers:

Charles Allen

Charles is a leading specialist in concrete engineering and construction materials with over 45 years’ experience. His experience includes the use of concrete for civil, building and tunnelling applications.

After several years working in the construction chemicals industry in Hong Kong, Singapore and Dubai, in 2000 he was appointed of Managing Director of the International Centre for Geotechnics and Underground Construction based in Zurich, a foundation responsible for the training and qualification of staff for tunnelling projects.

More recently, Charles has been involved as a consultant to several different organisations, within the civil engineering and tunnelling sectors and is currently advising joint venture contractors on the Deep Tunnel Sewer System, Phase 2 project in Singapore the Central Interceptor Tunnel in Auckland, New Zealand and the Thames Tideway project.

Charles is a fellow of the Concrete Society and a member of the ICT

Richard Sutherden
