May 17, 2019 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.

Oct 03, 2019 The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be

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

The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for ...

The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
