Q. How is the resistance to alkali-aggregate reaction (AAR) determined?

 

A. Alkali-carbonate reactivity (ACR) can be determined by ASTM C586, and alkali-silica reactivity (ASR) by ASTM C227, ASTM C441, ASTM C1260, ASTM C1567, and ASTM C1293. Refer to ACI 221.1R and the Appendix of ASTM C33 for discussion of these various tests.
