Compressive strength is only one characteristic of concrete that does not seem well understood by all. Project specificationsspecific limit of percent aggregate crushing valueThe tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the flexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality.
