Aggregate crushing value test determine . 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 .
Some important mechanical properties of GGBS aggregate was evaluated for its crushing and impact strength and compared with natural aggregates. The resulting aggregates were used as replacement for natural aggregate in concrete. The investigation results suggested that the GGBS aggregate showed a highest aggregate crushing value of 24% and aggregate .
Procedure of Aggregate Crushing Value Take a sample of aggregates by sieving through and retained on 10mm. The aggregate shall be tested in dry surface conditions. If dried by heating, the period of drying shall not exceed 4 hours and temp shall be 100110 deg C. A sample shall be cooled down to room temperature before testing.
This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.

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. The value is usually recorded up to the first decimal place. Aggregate crushing value 1 0 2 W W
Specifiion: 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.

· there are many physical and mechanical tests on aggregates performed as per is code provision (see is 383 for test requirement and follow the specified code for testing procedure) which specifies the size of the aggregate to be used for doing the test in which one of the criteria is aggregate passing from mm is sieve and retaining on 10 mm .
The aggregate crushing value was determined as per IS: . This test indies aggregate resistance to crushing under increasingly applied compressive load. The oven dried samples of about was filled in three layers with 25 gentle blows on each layer with rounded end of temping rod.
· The CBR is a penetration test for evaluating the mechanical strength of natural ground, subgrades and basecourses beneath new carriageway construction. It is described in UNEEN 103502:1995 [43]. The basic site test is performed by measuring the pressure required to penetrate soil or aggregate with a plunger of standard area.
Tests were conducted on aggregates including NA and RCA, to measure crushing value and water absorption, according to the China standard GB/T [ 21] which is similar to BS 812110 and BS EN 10976. Concrete At 28 days, three specimens a batch were used to provide a mean value as a test result.
Crushing Value Test Procedure Select clean and dry aggregate passing through mm and retained on 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.
