A recent survey of high-strength concrete bridges has revealed several structures with significant distress due to alkali-silica reaction (ASR) and a larger number with minor distress due to ASR. Since 1982, a study has been undertaken on conditions which encourage ASR and, more recently, towards developing accelerated laboratory testing which simulates the field performance of concrete structures. The main aims of the research are to prevent distress in new concrete structures and to develop monitoring techniques and repair procedures for existing structures. The main conclusion of the research is that Queensland Fly Ash is beneficial in reducing the magnitude of ASR expansion in concrete structures.
