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.
