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 cement concrete road. The aggregate whose crushing value is less than 40 can be used for wearing surface. This test must be ...
THEORY The aggregate crushing value gives a relative measure of the resistance of aggregate in bulk to crushing under a gradually applied compressive load. Crushing value is defined as the ratio of finess passing a standard sieve produced by crushing under standard condition to the weight of coarse aggregate expressed as a percentage.
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.

If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
