MORE DURABLE CONCRETE STRUCTURES
USING HOT DIP GALVANISED REINFORCING STEEL

by Professor Stephen R Yeomans, University of New South Wales, Canberra, Australia.

Singapore, October 23, 2008. Super Galvanising Singapore invited Professor Stephen R Yeomans to conduct a sharing session of the corrosion of steel reinforcement in concrete and strategies that can be adopted to avoid this insidious problem. During the session, Professor Yeomans discussed about how the corrosion of reinforcement is the most likely cause of the lack of durability of concrete and represents a significant expense in the maintenance and repair of concrete structures. If allowed to progress, reinforcement corrosion may also affect the structural integrity of the concrete itself.

Galvanizing is a well-known and widely-utilized method for the protection of steel reinforcement embedded in concrete. The history of the use of galvanizing steel in concrete extends over a period of more than 70 years. Recent experience indicates an increasing use of galvanized steel in a variety of concrete structures exposed to a range of environmental conditions including severe topical marine and industrial environments.

The seminar reviews the characteristics and use of hot-dip galvanized reinforcement. It covers its metallurgical characteristics and corrosion performance, design considerations, bond and load capacity, fabrication and handling, and showcases a range of world-wide applications. A key source of information to support the seminar is Galvanized Steel Reinforcement in Concrete, SR Yeomans (Editor), Elsevier, 2004. An overview paper extracted from the various chapters of this book is provided for quick reference.
