RP1020u1: Demonstrating the practical use of geopolymer concrete: high density coastal protection units

Project leader name: 
Professor Stephen Foster
Project status: 
Current
Project period: 
07/2017 to 07/2018

This project will demonstrate the use of the geopolymer concrete in a novel application, namely the construction of coastal protection (seawalls).

High density non-ferrous armour units (that do not require steel reinforcing) will be manufactured and cast on site and used as part of the repair of the Illawarra Port seawall which was damaged in the June 2016 east coast low. Project partners will supply the armour unit moulds, the bulk materials for geopolymer, the demonstration site, and the manufacturing and construction equipment. The CRCLCL is asked to fund the cost of monitoring and evaluation of the performance of the units, any necessary research to refine the process, and incidental materials.

This is a collaborative project that brings together industry partners (AECOM, Ash Development Association and the Australasian (Iron & Steel) Slag Association) and key industry stakeholders
and end-users (Illawarra Ports, UNSW Water Research Laboratory, Australian Climate Change Adaptation Research Network for Settlements and Infrastructure).A

Fact sheet
We have commenced a trial at NSW Ports’ Port Kembla Harbor to validate geopolymer concrete in the marine environment. A small batch of 18-tonne Hanbar units made from high density GPC have been cast and placed on the north breakwater. These units will be monitored for stability and integrity, and...
CRCLCL Project Reports
A major barrier to the adoption of Geopolymer concrete in construction is the lack of long-term performance data. Field testing can determine the behaviour of geopolymers in different service environments and address the gaps in knowledge. The University of New South Wales and Swinburne University...

Utilisation of Coal Combustion Product (CCP) from coal-fired power stations is of great interest in Australia. According to ADAA (Ash Development Association of Australia), in 2012, 12.8 Mt (million tonnes) of coal ash was produced from coal fired utilities in Australia [1]. Due to the increase...
