    Mar 31, 2017 · Source ( Read full article at) :-Aggregate Crushing Value test. IMPACT TEST ON AGGREGATES: Aggregate Impact Value test determines the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as toughness.


    Nov 03, 2013 · The aggregate sample: The material for the standard test consists of aggregates sized 20.0mm to 25.5mm. The aggregates may be dried at heating at 100 0 -110 0 C for not moe than 4 hours and cooled at room temperature before testing,if necessary.
