The manufacture of Portland cement in Australia is estimated to produce eight million tonnes of carbon emissions per year. Australia generates 14 million tonnes of fly ash and 3 million tonnes of slag as industrial by-products, which are not fully utilised but can potentially replace a significant amount of Portland cement. The main barrier to utilisation of these by-products is the Australian standards, which do not recognise concretes without Portland cement. This project will explore alternate pathways for low carbon concretes to be used with existing standards by developing a performance based criteria for concrete, which may not contain Portland cement.

The principal aims of this study are to review the existing fly ash utilisation industry and to examine the potential high volume applications of fly ash.
As part of the CRCLCL Program 1: Integrated Building Systems, pathways for adoption of low CO2 concrete are being identified. The objectives of the research described in this report were to examine the current state of the art in the design and specification of...
