In the existing aggregate testing method, it is a problem that a method capable of evaluating reactive aggregate including delayed expandable aggregate (which causes cracks in concrete after 10 years or more has passed) has not been established. Since it is necessary to evaluate the reactivity of alkaline aggregate of more effective aggregate, we will acquire the data as the basis based on the latest international information and consider the aggregate test flow for ASR potential evaluation .
