ABSTRACT
It is not difficult to recognise or to acknowledge the significant changes that have taken place in the field of concrete durability over the last 25 years. This period has seen an enormous growth in our understanding of the mechanisms and processes of deterioration, the ways in which to protect concrete against early deterioration and the effective utilisation of concrete-making materials that will enhance durability. Equally important has been the extent to which the advocacy of durability-as a fundamental property of concrete-has resulted in a conceptual change in the minds of those involved in the design and construction of concrete structures. For practitioners, concepts of durability are beginning to be woven into the everyday discourse of concrete technology.
