  • Abstract There are many carbonate rocks in Taiwan, but less study of alkali-carbonate reaction (ACR) in Taiwan. The research use the Canada chemical method (CSA A23.2-26A) to embryonic exploration the aggregates which may have alkali-carbonate reaction, and plan for second collect the aggregates. We proceed to treat ACR activity of the aggregates and analyze the applicability in Taiwan by the system of ASTM(ASTM C 586、ASTM C 1105、ASTM C 1293)、the system of RILEM(RILEM TC 191-ARP-AAR-2、RILEM TC 191-ARP-AAR-5)、the system of Canada(CSA A23.2-26A、CSA A23.2-14A)、the imitate autoclave method of China. Use micro-analyses(SEM、XRD)to assist identify activity of the aggregate, and use LiOH solution to discriminate AAR characteristic of the aggregate. The result of test show there are fourteen kinds of aggregates have ACR activity, and two kinds among fourteen kinds of aggregates which have ACR activity all have ASR activity. The system of ASTM and RILEM both adaptable to use to identify the aggregates which have ACR in Taiwan. Composite the result of test, and advance the procedure which adaptable to identify the aggregates which have ACR in Taiwan. First, using ASTM C 586 or RILEM TC 191-ARP-AAR-5 to scan for the aggregates if have ACR activity. If the aggregate is identified have no ACR activity, it can direct use in concrete. If the aggregate is identified have ACR activity, it need use ASTM C 1105 to finally identify if have ACR activity, and check it have no ACR activity before used.
