Alkali-activated 'geopolymer' concrete has been commercialised in Australia under the trade name E-Crete(TM) and is now finding acceptance among the end-user community and from regulatory authorities. E-Crete is derived from fly ash and blast furnace slag with proprietary alkali activators and is available in both precast and pre-mix forms. The pre-mix concrete is able to be placed using largely standard concrete processing equipment and expertise. A life-cycle analysis of E-Crete has shown savings of around 80% in CO2 emissions compared to a standard OPC-based binder, which provides the primary driver for the uptake of this technology on a larger scale. Commercialisation of geopolymer technology by Zeobond has been linked closely with both scientific research in this area and a broad process of industry and stake-holder engagement. The combination of these two activities will be highlighted throughout this article.
