Test method has not been maintained for late-expansive aggregates (which cause cracks in concrete after 10 years or more), in addition to the early-expansive aggregates which have been considered as the major cause of ASR in Japan. In order to confirm the effectiveness of the aggregate test method of JNES flow (the method mainly composed of international methods RILEM AAR - 3 and AAR - 4) and to prepare applicable aggregate test method, we conducted comparative tests using domestic and foreign aggregate...

Recently, many concrete structures such as bridge piers of the highway, damaged by Alkali Silica Reaction (ASR) have been observed in Japan. From this background, based on the latest knowledge of domestic and international, the ASR diagnostic method that emphasizes the petrological examination after the core sampling was proposed on Japan Nuclear Energy Safety Organization (JNES) report. In this research, in order to confirm the effectiveness of ASR diagnostic method for concrete structures proposed in JNES...
