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 100-degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.

Crushing Value Test: Form the result of crushing value we come to know that the recycle aggregate is having more resistance to the wear and tear than the natural aggregate.
