    Effects of Temperature Variations on ASR-Induced Expansive Behavior

    Although it is well established that the expansion of concrete due to the alkali–silica reaction (ASR) is very sensitive to temperature, and real structures are inevitably subject to temperature variations, st...

    Reconsideration of Required Studies on Predicting Long-Term Effects of AAR on the Performance of Real Structures

    This paper is based on the hypothesis that expansion due to alkali-aggregate reaction (AAR) is caused by alkali-silica gel (ASG) constrained inside the aggregate, which is produced by the alkali-silica reactio...
