In 2017, Austroads completed a four-year research project to provide a base for the use of geopolymer concrete in structural and non-structural applications. The project consisted of a review of literature and experimental work.
Geopolymer binders are produced by alkali-activation of a number of aluminosilicate precursors, including low-calcium fly ash and slag. Geopolymer concrete consists of similar ingredients as conventional concrete except that the cement is wholly replaced by geopolymer binder. Cement production emits high levels of greenhouse gases, and so reducing its use or replacing it with geopolymer binder has significant environmental benefits.
The webinar will outline the findings of the project and a current update of the use, monitoring and specification of geopolymer concrete by VicRoads over the past nine years.
You will gain an understanding of:
- Geopolymer concrete, its constituents and how it is manufactured
- Formulation and testing of numerous geopolymer recipes, and investigation of workability, strength development, mechanical behaviour, durability properties, abrasion resistance and ductility of reinforced geopolymer concrete
- The introduction of geopolymer concrete into VicRoads with several trial structural applications, general paving works and evaluation of performance.
Join in a live Q&A with the presenters to ask questions about geopolymer concrete.
Presented by Dr Ahmad Shayan and Fred Andrews-Phaedonos
Dr Ahmad is a Chief Research Scientist at ARRB, in the area of Durability of Concrete Materials & Structures and value-added utilisation of waste materials in concrete. He has written over 200 published papers and 350 technical reports and previously chaired the Standards Australia Committee CE/12 for 10 years. Ahmad was project leader for the Austroads project.
Fred is a Principal Engineer-Concrete Technology at VicRoads. He has worked for VicRoads for over 40 years and has been a technical specialist in areas such as concrete technology, concrete durability and bridge construction. Fred was project manager for the Austroads project.
