This paper studies the ACR reactivity of the carbonate aggregates in Taiwan. The results of XRD show that the mineral constituents of aggregates are mainly calcite and dolomite and the majority including quartz. The aggregates with ACR reactivity according to the results of ASTM C1105 are distributed in the area between Heping River and Siouguluan River. The results of CSA A23.2-26A and R1LEM AAR-5 result of single test and autoclave test are not consistent with the results of ASTM C1105, while the results of ASTM C586 and R1LEM AAR-5 determining procedure of ACR are consistent with the conclusions according to ASTM C1105. In practical, ASTM C586 or R1LEM AAR-5 can be used to identify the ACR non-reactive aggregates first in Taiwan, and then the reactivity of " reactive ACR aggregate " can be confirmed by ASTMC1105.
