General description. General description. The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing
BS 812:110, 812-11. 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.
Aggregate crushing value test apparatus is used for measuring the resistance of an aggregate to crushing. Made of Mild Steel. Cylindrical Cell, 150mm internal dia x 130 to 140mm height. Plunger, 148mm dia x 100 to 115mm height. Base Plate, 200 to 230mm square x 6mm thickness.
This testing method is known as an aggregate crushing value test. Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load.Coarse aggregate crushing value is the Sand equivalent test set: Aggregate Testing Lab Equipment
Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more
Sampling for Aggregate Crushing Value Test: For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate
This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate
Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test
Impact and Crushing Value Aggregate Crushing Value (ACV) Sets. UTA-0630 Aggregate Crushing Value (ACV) Set Ø 150 mm BS. UTA-0640 Aggregate Crushing Value (ACV) Set Ø 75 mm BS. The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate
The percentage mass of fines (passing a 2.80mm BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values
