Procedure of Aggregate Crushing Value Test:-. Sieve the test material through 12.5 mm and 10.0 mm IS sieve. Take test samples of aggregates passing through 12.5 mm IS sieve and retained on 10 mm IS sieve (minimum 3 Kg). Dry theme in an oven for 4 hours at a temperature of 100 °C to 110 °C and then cool at room temperature.

The amount of crushed aggregate with a grain size of over 20 mm is approximately 28% and the amount with a grain size in the range 10–20 mm is 72%. After crushing, the size of most of the aggregate was less than 20 mm. Such variation in grain size distribution can be important when recycled aggregates are used for compaction …
