Abstract:
AS3600, Concrete Structures, provides basic requirements for durability of structures which have design lives of 40 to 60 years, subject to some common exposure conditions. Other Australian design standards augment these requirements for durability of specific structures in limited environments, but frequently designers choose alternative service lives or supplementary properties using a combination of performance and prescriptive requirements. The wide range of different prescriptive and performance limits specified during the last 10 years in Australia indicates that there exists considerable uncertainty about how an adequate design life can be predicted. A large volume of research into this subject has been undertaken in Australia and overseas with the aim of determining short term tests and limits which are indicative of long-term performance. This paper reviews local test data which has been obtained from research programs and field evaluations in relation to design for marine durable, sulphate resistant or water retaining structures.
