Aggregate Crushing Value Test
Aggregate crushing value test provides strength of aggregates for resistance against crushing under loads and is used for roads and pavements construction.
Determination the Crushing Value of Aggregate test
The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load. It is a measure of the strength and toughness of the aggregate. In this test, a standard crushing load is applied to a prepared aggregate sample, and the percentage of fines generated after the specified amount of crushing is determined.

Aggregate Crushing Value – 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.
