Aggregate Impact value Test Apparatus, Procedure and uses .

The following description is a brief summary of the L.A. abrasion test. It is not a complete procedure and should not used to perform the test. The complete testing procedure can be found in: AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine; SummaryImpact test determines a very important quality of the test, i.e. ductility. Performing a Charpy test will give an estimate whether the metal is ductile or brittle. The way you are using Charpy impact tester determines the accuracy of the test results. There are some precautions that need to be taken while performing Charpy impact test.
