### Aggregate Crushing Value Test – Determine Aggregate ...

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 aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in …

### Aggregate Crushing Value - Civil Engineering

Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod. iii) The weight of aggregates is measured (Weight ‘A’).

### the crushing value of coarse aggregate purpose

Aggregate Crushing Value Test - Significance Test The primary purpose of using coarse aggregates is to enhance the strength of the concrete.Moreover, the coarse aggregates will easily blend with other concrete ingredients and make it as a homogeneous element. Aggregate Crushing Value Test - Significance Test...

### Crushing Value Of Coarse Aggregate Definition

Aggregate crushing value of coarse aggregate 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

### Aggregate Crushing Value Calculator, Test on course and ...

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. Where, W A is weight of surface-dry sample

### the purpose of aggregate crushing value test

Aggregate impact value test gives an indication of aggregates toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties 10 Exceptionally tough / Strong 10 – 20 Very tough ...

### Aggregate crushing value of aggregates with cement ...

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 method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. An aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger.
