Tag: aggregate reactivity Test methods for identifying aggregate reactivity

The first step in assessing the potential of an aggregate for AAR expansion and cracking is the performance of a petrographic analysis by a trained petrographer, the methodology being as recommended by a RILEM technical committee (Sims and Nixon, 2003). However, a petrographic analysis may not identify certain reactive materials (some may not be readily identified by optical microscopy), and
