Properties of ternary and calcined clay concretes: watch the opening day’s afternoon session from UKCS 2026

Following the release of the morning and lunchtime sessions, we’re pleased to share that the afternoon session from Wednesday’s seminar programme at this year’s UK Concrete Show is now available to watch on demand.

Delivered in the Concrete Connect Seminar Theatre, this session explores how ternary cement combinations and calcined clay concretes are helping to reduce embodied carbon while maintaining concrete performance, durability and long-term service life.

Chaired by Claire Ackerman, Chief Executive Officer of The Concrete Society, the session features presentations from Gareth Wake and Apostolos Tsoumelekas, followed by a panel discussion and Q&A with Simon Chudley and Prof Leon Black.

Representing organisations including MPA, Skanska UK, LKAB Minerals, and the University of Leeds, the speakers share insights from current standards development, research and real-world infrastructure projects.

The session covers:

• How ternary cement combinations are implemented through UK concrete standards

• The impact of binary and ternary combinations on durability and embodied carbon

• Performance insights from calcined clay concrete trials and UK infrastructure projects

• Lessons learned from the REAL and Ex-Clay innovation programmes

• A panel discussion exploring the future of cementitious materials in low-carbon construction

Whether you attended the session live or are catching up online, this is an opportunity to hear directly from industry and academic experts working at the forefront of lower-carbon concrete development in the UK.
