The current design standards for concrete represent a major step forward in the area of design and specification of durable concrete structures. However, evidence suggests that these provisions have not been universally understood and adopted in practice. Research into all aspects of the complex issue of durability of concrete has produced, during the last decades, an unprecedented volume of information. Despite the undeniable progress in understanding the problems and developing processes leading to improved durability, it is generally accepted that the interrelationship between the steps required in design, detailing, concrete technology and above all construction aspects have not yet been mastered sufficiently to ensure that the desired product, durable concrete, is achieved in all cases. A number of issues related to the relationship between the primary research and durability of concrete structures are discussed. It is envisaged that future actions to improve concrete durability will include a greater level of education and technology transfer to the industry to emphasise issues such as the links between durability and curing, the further development and implementation of durability plans and the further development of criteria for concrete repair materials and methodologies. Contractually sustainable indicators of long term concrete durability performance will be sought. (A)
