### Importance Of Aggregate Crushing Value Test

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.Between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria Such a mathematical relationship usually established through regression modelling on data collected is useful in saving time and money cost on site through estimating one variable when another is known.

### Correlation Between Aggregate Crushing

If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate Whereas if the crushing value is 35 or above it would normally be considered as weak aggregate After performing the test the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of.

### Meaning Of Aggregate Crushing Value

This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test Importance of Impact Value Test Generally the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.Calculation of aggregate crushing value The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2 36mm sieve) to the total weight of sample expressed in percentage W1= Weigh of the total aggregates (Wa We) W2= Weigh of aggregates passing through 2 36mm IS sieve.
