Abstract:

In the past 5.5 years, the Texas Department of Transportation (TxDOT) spent approximately $2 million for recasting precast concrete products that had alkali-silica reaction (ASR). Aggregates belonging to false positive and negative categories based on the current test methods are gradually growing. Therefore, the demand for a rapid and reliable test, which can assess aggregate ASR potential at various alkali loadings, is high. This study developed a fast, reliable test method to determine aggregate alkali-silica reactivity based on the time-dependent nature of the onset and speed of reaction.
