Aggregate Crushing Value Test - Significance & Test Procedure

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100

Aggregate Impact Value Test (IS:2386 (Part IV

The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregate differs from its resistance to a slow compressive load. The test sample consists of aggregate the whole of which passes a 12.5 mm sieve and is retained on a 10 mm sieve.

Aggregate Crushing Value Test – Determine Aggregate Crushing

The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.
