### Solved The aggregate crushing value for concrete as per

Crushing test. Gives a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. The aggregate crushing value should not be greater than 30 for the surface course and 45 for the base course; Impact Test. Gives a relative measure of the resistance of an aggregate to suddenly applied load.

### aggregate crushing value requirements for concrete

The tests for Aggregate Crushing Value ACV and FACT 10 Fines Aggregate Crushing Test measure the crushing strength of broken rock. These results do not necessarily relate to the ﬂexural or compressive strength of concrete made with that aggregate but are a useful index of overall quality. Normal values for ACV range from 14 to 30 and for.

### Aggregate Crushing Value Test Significance amp; Test

Calculation of Aggregate Crushing Value. 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 W2W1 x 100.
