Low carbon geopolymer concrete hanbar project

The UNSW project came about in early 2016 when researchers began looking at innovative ways to use industrial by-products such as steel slag in the production of large scale infrastructure. As a result of effective collaboration across industry and research, fourteen 18-tonne Hanbar units made from high density low carbon geopolymer concrete were cast and placed on the northern breakwater at Port Kembla Harbour. These units are monitored on an ongoing basis for stability and integrity (in comparison to the units made up of the traditional concrete mix) and are providing a valuable benchmark for the future use of geopolymer concrete.
