Concrete In Australia : September 2013
26 Concrete in Australia Vol 39 No 3 CONFERENCE TECHNICAL PAPERS Gold Members Concrete 2013 to offer a variety of topics e Concrete Institute of Australia s agship event, the 26th Biennial Conference, is to be held on the Gold Coast between Wednesday 16 and Friday 18 October. e conference has been organised by a very experienced and capable committee headed by conference chairman Emeritus Professor Peter Dux, which includes a very rich and diverse technical program. In this issue of the magazine, we have put together a sample of full and shortened versions of papers to provide the avour of the type of high quality papers which will be presented at the conference. Topics covered include the use of corrosion monitoring probes, structural mechanisms associated with dome performance, e ciency of bre reinforced polymer (FRP) strengthening systems, new design and construction techniques and various aspects of geopolymer concrete, including barriers to implementation, review of properties and in-situ performance. e rst paper in this issue by Marita Berndt et al discusses the ndings of a survey which identi ed barriers speci c to geopolymer concrete and potential actions to overcome in identifying pathways for adoption of low CO2 emission concrete and contribute to reduction of emissions in the built environment. e second paper by Ahmad Shayan et al discusses the ndings of an investigation undertaken into cast in-situ geopolymer concrete which involved electrochemical measurements carried out on the geopolymer components, as well as laboratory testing and examination of the concrete to determine its properties with respect to strength, durability, chemical composition and microstructure. e third paper by Andrews-Phaedonos et al discusses the value of utilising corrosion monitoring sensors to monitor the e ectiveness and ongoing performance of various durability provisions incorporated in new bridge construction, as well as the e ectiveness and ongoing performance of various rehabilitation and repair techniques. e rst shortened version of a paper by Doug Jenkins discusses the signi cance of the interaction of daily and annual thermal strain cycles with ratchet mechanisms in the stone and brickwork of domes, and the implications for restoration and strengthening techniques. e second shortened version of a paper by Lucas Wise et al discusses some interesting design and construction techniques for the South Road Superway. e third shortened version of a paper by Scott T. Smith presents key research ndings into anchorage devices made from FRP and discusses the physical behaviour and techniques which can be used to further enhance the e ciency of FRP strengthening systems. As guest editor, I would like to take this opportunity to thank all the authors who have contributed these papers and wish them all the best at the upcoming conference. Finally, I encourage all members to take advantage of the many opportunities that this conference provides and register to attend in October, on the beautiful Gold Coast in Queensland.
