Aggregate - AfriSam

The 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. Normal values for ACV range from 14 to 30%, and for
