Abstract:
In Australia, the major population centers are located on the coast. A significant proportion of the nation's heavy industrial infrastructure and civil engineering work is also coastal. A wide variety of structures have been constructed in aggressive marine environments. Many of these structures have had long histories of durability problems and subsequent repair. Paper reports on field and laboratory studies that have been carried out to evaluate the performance of two wharf structures and their repair systems. It discusses the usefulness of various methods of detecting corrosion activity and considers the effects of chloride contamination and carbonation on damaged structures. Some aspects of repair materials for use in the marine environment are considered.
