RP1020u3: Mainstreaming of Geopolymer Concrete for Pavements

This project builds on the backbone and success of projects RP1004 and RP1020. In mid-2018, and as a direct outcome of RP1020, the Handbook for Specification and Design of Geopolymer Concrete will be complete – this succeeding project embeds the outcomes of this work with large scale demonstration applications in pavements. Working with industry partners City of Sydney, Ash Development Association, and the Australasian (Iron & Steel) Slag Association, large pavement sections in Sydney will be cast, using knowledge generated in RP1020, and monitored for performance.

RP1020u3: Installation of Geopolymer Concrete Pavement at Wyndham Street for City of Sydney: Interim Report Project

This project represents the third and final stage of a seven-year program by the CRC for Low Carbon Living for the mainstreaming of non-traditional concrete and its delivery to practice; more specifically Geopolymer concrete (GPC).

The project showcases the potential for green construction materials through delivery by a major Australian Council, and Industry Partner the City of Sydney, in the adoption of Geopolymer concrete as “conventional” practice. The project further demonstrates the capacity to deliver on the council’s stated objectives for the use of “Sustainable Materials in Concrete”.

This interim report details the installation of the pavements, the GPC materials properties, the installation of gauges and initial surface scanning undertaken for monitoring of long-term performance. The project will be on-going over the next five and more years to evaluate performance under high volume and heavy vehicle traffic loading.
