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.
Calculate Aggregate Crushing Value The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A ×100 W B W A × 100
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions.
"Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load" In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be determined and used instead.
Jan 07, 2019· How Concrete Is Recycled . Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.
Aggregates Crushing Value Test. This percentage is known as a crushing value of aggregate this percentage should not exceed 30 of the total weight of aggregate taken for the test the aggregate crushing value test result should not be more than 30 for the concrete .
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 should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for ...
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 .
Jun 27, 2020· The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.

Feb 15, 2019· Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.
Aug 02, 2018· 1. Crushed tile as an aggregate possesses some qualities of a good aggregate. From the results of the study, the aggregate crushing values and aggregate impact values of crushed tiles were 23.38% and 25.19% which are less than 30% according to standards and it is therefore suitable for concrete applications. 2.
Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on .
