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.

Impact and Crushing Value Aggregate Crushing Value (ACV) Sets. UTA0630 Aggregate Crushing Value (ACV) Set Ø 150 mm BS. UTA0640 Aggregate Crushing Value (ACV) Set Ø 75 mm BS. The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load.

The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.

THE DETERMINATION OF THE AGGREGATE CRUSHING VALUE 1 SCOPE The ACV of an aggregate as defined hereunder is determined by crushing a prepared confined aggregate sample under a specified, gradually applied compressive load and determining the percentage of the material crushed finer than a specified size. Definition The aggregate crushing value ...

Enhancement of Pilot and Automax compression machines for ACV test Aggregates Crushing Value test according to BS 812:110 BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load .

The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (WaWe) W2= Weigh of aggregates passing through IS sieve.

The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of the sample expressed a s a percentage is defined as Aggregate Crushing Value.

aggregate crushing value Structure Impact crusher uses impact energy to crush materials. aggregate crushing value Features 1, Multiple chamber can make it evenly and suitable for crushing hard rock. The coarsely crushed stones are sent to the impact crusher by the belt conveyor for further crushing.

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.

Aggregate crushing Value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Ten Percent Fines Value used for testing aggregate smaller than 10 mm. Comprises: 150 mm or 75mm diameter steel …

AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – , 10mm and

Nov 03, 2013· The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under agradualy applied compressive load. It s the percentage ...

Aggregate crushing Value =(W B /W A) × 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety Precautions: Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes helmet during the time of test.

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS

Feb 04, 2011· The aggregate crushing value is defined, as a ratio of the weight of fines passing the specified IS sieve to the total weight of the sample expressed as a percentage. 100 W2 Where, W1 = Total weight of dry sample.
