This report examines in detail the relevance of cracking in concrete to the corrosion of reinforcement.
The first edition published in 1995 was principally as a response to the BRE publications which suggested that cracks in concrete structures can give rise to reinforcement corrosion. Since all concrete structures contain cracks, this implied that reinforcement corrosion was inevitable. The conclusion was thought to be contrary to practical experience which tended to suggest that, in the vast majority of cases, corrosion damage did not occur during the service life of the structure.
At the time the report was published it provided some clarity to the subject and formulated guidelines to help classify crack types on the basis of their potential to give rise to corrosion in the future. In this new edition, the discussion has been reassessed and where appropriate the text amended, new text provided and references updated to bring it in line with current thinking.
