aggregate crushing value discussion RESULTS Aggregate crushing value of the material tested = SPECIFICATION As per IS:2386 part4-1963. . and A = weight of surface-dry sample.The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage.

The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS: 2386 (Part IV)1963,IS Sieves of sizes 12.5mm, 10mm and 2.36mm, A cylindrical metal measure of 75mm dia. and 50mm depth, A tamping rod of 10mm circular cross section and 230mm length, rounded at one end and Oven.

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm. sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm. sieve is subjected to crushing under a gradually applied compressive load of 400 kN.

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.

TEN PERCENT FINES TEST AND AGGREGATE CRUSHING TEST DISCUSSION (a) Report the aggregate crushing value and ten percent fines value. conclusion of aggregate crushing value Other than the gradation, the aggregate crushing value (ACV) is the relative measured of the resistance of the aggregate to CONCLUSION.

The aggregate impact value (AIV) is B AIV = × 100 (%) . . . (1) ARESULTSAn average is taken of the two tests and the result is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose.

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.
