Crushing Value Test of Aggregates  Importance,
2021718 Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.

How to Determine the Aggregate Crushing Strength Value
2018426 Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.

The shape of an aggregate is very important in crushing tests. Dexter and Kroesbergen (13) emphasized that a major source of variation in crushing force was due to the variability in aggregate shape. In general, researchers working on aggregate strength against crushing forces have assumed that the shape of aggregates is spherical (10).
