The ultra-accelerated mortar-bar test (AAR-2) has been widely and successfully used as a screening test to identify aggregates that are potentially alkali-reactive. However, there are exceptions; some aggregates that, though alkali-reactive according to both field experience and concrete prism test results, do not show as such in the mortar-bar test. Trials carried out by members of RILEM TC 191-ARP have established that these aggregates include carbonate materials. It has been found that any… Expand
