· Procedure. Take the sample aggregate. Pass the sample with 12.5 mm sieve and retained on 10 mm sieve. Fill the Cylinder Cup (Diameter 75 mm Depth 50 mm) in three layer with 25 gentle stroke each with tamping rod (10 mm in diameter and 230 mm long). Now Weight the Sample (i.e. Weight of Sample and Cup – Weight of Empty cup) = W1 gm.

Aggregate Impact Value (AIV) The apparatus has been designed in a particularly heavy duty form, with specially hardened steel surfaces for minimum wear. The assembly is heavily plated to ensure corrosion resistance and forms a rigid frame around the quick-release trigger mechanism, which ensures an effective free fall of the hammer when released.
