SUMMARY
This project is testing a new type of recycled concrete that uses carbon-conditioned recycled aggregate to improve its strength and durability. Developed by Western Sydney University and now scaled up by RMIT for field trials, this concrete aims to reduce environmental impacts while offering strong performance. Early tests show promising results, with better properties than standard recycled concrete. Cement Concrete and Aggregates Australia is the key industry partner, supporting field trials and potential future use.
OPPORTUNITIES
Access to research funding for advancing carbon-conditioned concrete technology
Real-world trials could lead to industry-wide use of more sustainable concrete
Strong partnerships between universities and industry can speed up innovation and adoption
