TEST. In conclusion,the percentage of aggregate’s wear depends on the quality of aggregate. In this test, we can conclude that: The loss of aggregate = 1663 g. The percentage of wear = 33.26%. Lower abrasion loss values indicate the aggregate was tougher and more resistant to abrasion.

Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
