Austroads: Transport Research and Trends

Properties of General-purpose Cement with Increased Percentages of Limestone

This webinar provides an overview of an Austroads project that investigated whether cements with elevated limestone content would perform satisfactorily in ambient-cured and precast concretes subjected to aggressive exposure conditions.

The webinar was presented on 15 October 2019 by Dr Ahmad Shayan and Fred Andrews-Phaedonos. 

Geopolymer Concrete and its Applications

This webinar outlines the findings of an Austroads geopolymer concrete project and a current update of the use, monitoring and specification of geopolymer concrete by VicRoads over the past nine years.

It covers:
• 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.

The webinar was presented on 1 May 2018 by Dr Ahmad Shayan and Fred Andrews-Phaedonos.
