Geopolymer and High Volume Fly Ash Concrete for Pavements

Paper and Presentation by Marita Berndt & Gavin Chadbourn from ASCP 3rd Concrete Pavements 2015

Much interest has been shown in improving the sustainable performance of concrete. The use of cement replacement materials and geopolymer concrete offers benefits in terms of reduced carbon footprint and enhanced properties.

This paper reviews the properties of geopolymer concrete and concrete with high levels of cement replacement materials relevant to pavements and issues to overcome to enable widespread use. Recent progress towards preparation of a handbook in association with Standards Australia to provide guidelines on use and specification of geopolymer concrete are presented.
