Concrete In Australia : September 2008
CONFERENCES Corrosion conference to target asset management The recent gas pipeline explosion in Western Australia has once again highlighted the importance of regular asset management, and the need to keep up-to-date with the latest technology. Ensuring regular inspection and forward planning is incorporated into an asset’s life plan not only saves money in the long term, but can help avoid the potential for disaster. When implementing an asset management plan it is important to remember that any plan is a “work in progress”. Changing methodology, advances in technology and most importantly changes to Australian Standards and the law mean that what is appropriate at the commissioning of a project is not always the best practice when it comes time to conduct maintenance. Continuing education on best practice methods is widely recognised as saving money in the long-term life of a project. According to Michael Boardman, the president of the Australasian Corrosion Association, regular and thorough maintenance and inspection using the most current technology and guidelines goes a long way to preventing costly repairs when something goes wrong. “Many examples can be cited where substantial costs have been incurred when proper maintenance has been neglected. A couple of years ago, Auckland was plunged into darkness when a shackle at the Otahuhu Power Substation parted company, dropping an earth wire over the switchyard and causing a massive power blackout. It was a whole day before power was restored to Auckland, and based on my rough calculations, the cost to the New Zealand economy was close to NZ$48 million – all for a $10 shackle,” he said. While this is a dramatic example of where massive costs were incurred in what was by all accounts an avoidable incident, it does highlight how important even the smallest shackle can be in the bigger picture. Due to the high costs associated with corrosion in the construction industry, and the importance of the concrete construction industry to Australia’s economy, the Australasian Corrosion Association regularly incorporates a concrete stream at its annual corrosion conference. This stream is a forum for concrete and construction industry professionals such as engineers, scientists, researchers, consultants and manufacturers to present the latest in corrosion prevention methods and products, as well as advances in Combining case studies, research papers and reviews, the concrete stream is the industry’s most comprehensive corrosion educational tool. cutting edge research.

The stream also includes many papers by industry professionals who are actively involved in the conducting Advanced corrosion in a reinforced concrete bridge ... the Australasian Corrosion Association’s annual conference in Wellington, New Zealand in November will include a stream for concrete and construction industry professionals. of corrosion inspection and applying and using corrosion prevention products. These product end users offer a valuable insight into how products and construction techniques are put to their best uses, or alternatively what to avoid. Some paper highlights from the program include: • Extension of design life of existing maritime infrastructure – a durability perspective from Maunsell Australia and Patrick Ports; • Galvanic corrosion control solutions for reinforced concrete patch repairs from Parchem Construction Products • A review of design and performance criteria requirements for the cathodic protection of concrete structures from Maunsell Australia and Savcor ART • Concrete degradation in prestressed concrete bridge piles from Opus International Consultants and ARRB • Galvanic liquid applied coating for the protection of concrete reinforcement from Cortec Corporation, USA; • Electrochemical techniques: methodology for studying the corrosion performance of reinforcing steel in inorganic polymer mixes from Quest Reliability • Cathodic corrosion protection of precorroded steel in concrete with galvanic zinc anodes from the University of Applied Sciences, Germany; • The use of Continho Rings and other shrinkage measurement methods in developing repair mortars to meet EN 1504 from BASF Construction Chemicals. The 2008 ACA annual conference will be held in Wellington, New Zealand from 16-19 November. For a preliminary brochure and further conference details, please visit www.corrosion.com.au.
