Jan 27, 2019· The crushing value of aggregate is very important to know the strength of the aggregate. For finding the resistance of aggregate under gradually applied compressive load, the crushing value test of aggregate is done. For the crushing value test, the following procedure is followed.

7 Lab Test on Aggregate Should Satisfy for Use in Concrete. The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing ...

Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.
