Aggregate Impact Value Test Apparatus is used to determine agreegate impact value of coarse aggregate.
The hammer of the tester fall freely from 380 mm height on coarse aggregate for 15 times/15 sec.the crushed aggregate removed from the cup ,then sieved and weighed. The % ratio of the weight passing 2.36mm sieve and weight of oven dried sample is Aggregate Impact value.

TICOM 612 Aggregate Impact tester as per IS: 2386 (IV)
It consist of a circular base and support coloumns constructed to form a rigid frame around the quick release
“trigger” mechanism for a free fall of the hammer, a cylindrical
steel cup having a hardened inner surface 102 MM I.D.
X 50 MM deep a metal cylindricl measure 75 MM I.D.
X 50 MM deep,a tamping rod 10mm diameter X 230 mm long.

Spares :
