Mechanical Properties of Aggregates
Aggregate Crushing Value Apparatus
IS 2376 (PART-IV) & BS 812:111
For Measuring of Resistance of Aggregate to Crushing.
The Aggregate Crushing Value (ACV) test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. All parts of the apparatus are powder coated or galvanized steel, heat treated and ground before manufacturing to make it durable and reliable.
Consists of M.S. Cylindrical Container 150mm +/-0.5mm dia x 130mm to 140mm high with base plate 200 to 230mm/sqr x 6mm thick. A Plunger of 148mm +/-0.5mm dia x 100 to 115mm high. Supplied complete with Tamping Rod, 16mm dia x 600mm long, both ends rounded, 1 no. Metal Measure 115+/- 0.5mm dia x 180 +/- 0.5mm high.
Note :
On Special Request Aggregate Crushing Value Apparatus having 75mm dia or 300mm dia cylinder size can be supplied.

Aggregate Impact Tester With Blow Counter
IS 2386 (PART IV) 9377 & BS 812:112
It is robustly designed to determine the aggregate impact value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. The counter fitted to the machine automatically records the number of blows delivered to the sample, manufactured from heavy duty plated steel to resist corrosion.
