Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. The aggregate Crushing Value Test is an important test to be performed on aggregate. The strength of aggregate parent rock is determined by
Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To
Aggregate crushing value = (W2 x 100) / (W1W) W2 =Weight of fraction passing through the appropriate sieve W1W =Weight of surface dry sample. The mean of two result to
This test was performed in two trials, as required in the standard, and the related test results on RCA, RAP and basalt and the average crushing values for each aggregate type are
Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the
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
Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surfacedry sample; W B is weight of fraction passing the appropriate sieve; Reporting of Results. The mean of the two results shall be reported to
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird of the cylindrical measure in three
A lower crushing value indicates a lower crushing fraction under a specific load and would give a better result, longer service life and economic performance.
The ‘aggregate crushing value’ gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of
Crushing value is a crucial metric for aggregate strength and, as a consequence, concrete mechanical performance. Figure 5 shows that the average aggregates crushing value outcomes for NA and RA with varying numbers of screenings. The crushing values obtained for RA samples were higher than for NA samples,
Strength indices such as point load index, impact strength index, aggregate impact value, aggregate crushing value and durability indices such as slake durability index, aggregate abrasion value are the furthermost parameters being evaluated and applied for engineering structures, building stones and construction aggregates.
Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse
Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surfacedry sample; W B is weight of fraction passing the appropriate sieve; Reporting of Results. The mean of the two results shall be reported to
The average aggregate crushing value (ACV) and the aggregate impact value (AIV) obtained from the evaluations is 28.7% and 29.5% respectively and are within the acceptable standard limits. The specific gravity and water absorption gave average values of 2.60 and 0.22% respectively while the flakiness index obtained from the analysis is 26.7%.

To calculate aggregate Crushing value by testing aggregate passing 12.5 mm sieve and retained on a 10 mm sieve. Scope of Aggregate Crushing Value. The specific gravity of aggregates normally used in construction ranges from about 2.5 to 3.0 with an average value of about 2.68.
The global Rock Crushing Equipment market size was valued at USD 6070.4 million in and is expected to expand at a CAGR of 8.04% during the forecast period, reaching USD 9653.83 million by
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. Aggregates with lower crushing
The average value of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety and Precautions While Testing: Before testing, check the testing machine.

Crushing Value Test Procedure. Select clean and dry aggregate passing through 12.5 mm and retained on 10.0 mm sieve. Weight the empty cylindrical measure. Let the weight be ‘a’ grams. Fill the aggregate in the cylindrical measure in three layers, tamping each layer 25 times with the rounded end of the tamping rod.

The ‘aggregate crushing value’ gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of ‘aggregate crushing value’ 30 or higher, the result may be anomalous, and in such cases the ‘ten percent fines value’ should be determined instead. The average of the
