    Abstract

    Alkali-activated “geopolymer” concrete has been commercialized in Australia, and it is meeting with strong demand from the end-user community and approval from regulatory authorities. Interest in the application of this technology throughout the Asia-Pacific region is growing, as end-users, engineers, and architects increase their environmental awareness and as some jurisdictions introduce a carbon tax or carbon pricing policy. VicRoads, the roads authority of the state of Victoria in Australia, is a signature specifier that has already changed its specification for non-structural concrete to accommodate geopolymer concrete. In addition, progress has been made in a RILEM Technical Committee to establish a framework for a performance standard for alkali-activated concrete. The commercialization of geopolymer technology is linked closely with scientific developments in this area, in particular through the use of innovative methods to analyze and predict durability and in understanding and controlling reaction mechanisms. The importance of leading-edge scientific research in enhancing the performance and utility of geopolymer concretes is also highlighted, with the identification of some of the remaining technical and non-technical hurdles that must be overcome. This paper outlines the process of commercializing an alternative binder system at the production scale, including obtaining regulatory approval for groundbreaking applications in civil infrastructure. There has been much discussion of the potential of alkali-activation technology over the past decades, but until now, large-scale application has been limited. Some of the reasons for this slow progress, as well as the methods by which obstacles have been overcome, are discussed.
