Half time drinks

Speaker 3Dr Ahmad Shayan – Director/Structural Engineer/Durability Design & Service Life Modelling Specialist and will be presenting on “Structural & Durability Assessment of Transport Concrete Infrastructures”.

In previous occupations he was Chief Research Scientist at the Australian Road Research Board (ARRB), for over 22 years, and prior to that Senior Principal Research Scientist at CSIRO for 16.5 years.  He has over 40 years of experience in research and consulting on the various aspects of concrete technology, deterioration of concrete structures, and methods of preventing durability problems in concrete structures. Ahmad has published some 220 papers in national and international scientific media, and has written over 400 technical reports for government and industry clients. Dr Shayan was chairman, Standards Australia Committee CE/12 for over 10 years in the 1990s and early 2000s, has served on the international organising committees of many international AAR conferences, and was chairman, 10th Int. Conf. on AAR, Melbourne, 1996. He is a foundation member of the Rilem Technical Committee TC 191-ARP for accelerated AAR testing, and a member of the International AAR Committee. He was Adjunct Professor at the Departments of Civil Engineering at Monash University and Swinburne University since 2009, and joint supervisor of Ph D students in his areas of expertise.the prestigious Clunies Ross Medal in 2003, for his work on durability of concrete structures and for contribution to the economic well-being of Australia.

  • Joint winner of Engineers Australia, Kevin Stark Memorial Award (2009) in conjunction with NZ colleagues for a paper on Concrete Degradation in Precast Concrete Piles.
  • Winner of Inaugural Lifetime Achievement Award, Australian Roads Research Board, July 2017

Speaker 4Amy Lezala Zahr -LSRG Engineering Manager, Metro Trains. Amy has been in rail since 2007, working across rolling stock maintenance, rolling stock manufacturing, infrastructure design assurance and network asset management. Amy has worked in safety and assurance for the majority of her career, from her early days as a rolling stock fire safety engineer to her current role as Level Crossing Engineering Manager at Metro Trains Melbourne. She takes a whole of life, whole of system view when approaching a project. It is important to Amy that we consider the life cycle of our assets to ensure that we get the most sustainable solution.

This is event is sponsored by Duoguard Australia

And of course, this event includes networking drinks and canapes.

What is Alkali-Aggregate Reaction (AAR) in Concrete
AAR is a concrete deterioration mechanism, caused by the reaction of certain aggregates and alkali hydroxides which are generated during the hydration of Portland cement. Susceptible aggregates usually contain unstable forms of silica (i.e., amorphous or disordered silica minerals). The reaction product, which forms in the presence of moisture, is a hydrous alkali-silica gel that has a larger volume than the original volume of the reactants, thereby causing expansion and leading to cracking in the concrete.  Factors that affect the severity of the reaction and concrete cracking include the type of aggregate, amount of reactive component in the aggregate, amount of available alkali in the concrete, availability of moisture and the reinforcement level in concrete.  Apart from cracking, AAR can adversely influence the functioning of the affected structure, including distortion, misalignment of installations, rotation, jamming of clearances, etc., which can result in heavy maintenance costs and significantly reduced service life.  The presentation by Dr Ahmad Shayan will cover some of these issues and discuss methods of prevention and remediation of AAR-induced damage to structures
