Abstract:In the past, concrete was considered a material with a long-lasting and functional in situ life. More recently, many durability and serviceability problems in structures have been reported. Codes and standards relating to both plain and blended cement concretes are currently being written in Australia, where new durability design requirements have recently been formulated. The long-term performance of both plain and blended cement concretes in structures has at this stage not been quantitatively defined. This paper briefly discusses methods that have been developed to aid in determining the durability of in situ concrete structural elements. Consideration is given to correlations between reinforcement corrosion occurrence in building structures and coastal proximity. The effects of fly ash usage in concrete on other aspects of the durability of structures are also considered. Data relating to the durability of a series of inspected structures are presented. Attention is drawn to existing and potential durability and serviceability issues. Wherever possible, comparisons are made between the relative performances of plain and blended cement concretes.
