In a world-first project with NSW Ports, the CRC for Low Carbon Living has incorporated waste from coal-fired power stations into low carbon Geopolymer concrete barricades to protect the coastline at Port Kembla from extreme weather events. Aimed at validating the use of a special high-density Geopolymer concrete in marine environments, the 17-tonne Hanbar Geopolymer units will be monitored for stability and integrity, providing a valuable benchmark for the future use of this unique material.
