Aggregate impact and crushing test

6. Impact, 10% Fines & Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries, e.g., Australia and New Zealand, only use the latter test.
