Research Abstract |
The Alkali-Silica Reaction(ASR) is known as a reaction which occurs in concrete between the highly alkaline cement and reactive silica aggregates and causes serious expansion and cracking in concrete, resulting in critical structural problems. In this study, the ASR was confirmed in the artificial condition by using the X-ray Absorption Fine Structure(XAFS) spectroscopy. And, the experiments of RC beams clarified the effect of ASR expansion on loading capacity and bond performance.
