论文简介： In recent times in many parts of the world, reinforcement corrosion has become the main factor in early, premature deterioration, and sometimes failure, of concrete structures. One of the major factors contributing to this deterioration process is the environmental and climatic conditions to which a concrete structure is exposed. When the severity of environment is compounded with poor quality concrete and/or defective design and construction practices, the process of deterioration becomes interactive, cumulative and very rapid, and a cancerous growth that cannot be easily stopped. The poor durability performance of many concrete structures is causing disruption and expenditure on remedial works which owners and society cannot afford and do not wish to see repeated.
