Dr. Akio Kasuga is an Executive Vice President and CTO of Sumitomo Mitsui Construction. He has designed and built more than 200 bridges throughout his distinguished career. Significantly, he has developed many new bridge design and construction technologies including extradosed bridges and butterfly web bridges, and has more than eighty patents. He received awards from the International Federation for Structural Concrete (fib) for “Outstanding Structures” n 2006 and 2018, and the Eugene Freyssinet Trophy in 2013. He is currently the President of fib from 2021 to 2022.

Dr. Kefei Li works in Civil Engineering Department of Tsinghua University as tenured full professor, and principal investigator (PI) of the research group of building materials. His research fields include the physical and mechanics of cement-based materials, the durability of concrete materials and structures and the life-cycle engineering of concrete structures. He obtained his Ph.D degrees from Tongji University (2000) and Ecole Nationale des Ponts et Chaussees, Paris (2002). He leads multiples national projects of research, publishes 70+ SCI papers, heads the draft team of the durability standards of China, and serves in the editorial boards of Cement and Concrete Research, Materials and Structures and Journal of Engineering Mechanics (Part B: Nanomechanics and Micromechanics). He is now the convener of China Region of RILEM.

This presentation will cover different technically justified ways to manage design and construction to optimize the use and performance of concrete that will be exposed to potentially high risk temperature conditions during construction. Emphasis will be given to the implementation of requirements, guidelines and best practices described in ACI and CSA industry standards. The thermal aspects of concrete will be focused on hot/cold weather and mass concrete, including its potential impact to concrete properties and performance. Examples of ways to improve thermal control measures, concrete materials, mixture proportions, production (batching), construction (placing finishing and curing), DEF mitigation, durability properties, service life performance, resistance to cracking, among others, will be presented from the field practitioner perspective using real-world examples and case studies from recent projects.

Stuart Matthews is Convenor of fib Task Group 10.1, which is the group responsible for preparing the next edition of the fib Model Code for Concrete Structures (which has a working title of fib Model Code 2020). At different times Stuart has served as chairman of the then fib Commission 5: Structural Service Life Aspects; fib Special Activity Group 7: Existing Concrete Structures; and more recently fib Commission 3: Existing Concrete Structures.

Stuart was awarded the fib Medal of Merit in 2016. He is also an Honorary Member of fibUK.
Amongst his other publications, Stuart was a contributing author to the widely known and acclaimed Institution of Structural Engineers (London) document “Appraisal of Existing Structures”, for both the 1996 and 2010 editions. Stuart received the Institution of Structural Engineers’ Clancy Prize and Medal in 2013.

Stuart is a chartered civil & structural engineer and also a chartered scientist. He has worked in various fields including civil engineering and building, heritage structures, full-scale structural testing, structural service life assessment, non-destructive testing & investigation, as well as the deterioration, repair, rehabilitation, maintenance and structural strengthening measures to extend the useful life and durability of concrete structures. He has undertaken research consultancy & expert witness commissions on a range of matters and has also made various forensic, durability, fire and accident investigations, including a number of structural collapses.

Stuart worked at the Building Research Establishment in the UK between 1992 – 2017. Previously he had worked within the UK water industry, for a specialist testing house, for an international consulting firm and a UK building contractor.
