arse aggregate with determination of crushing value

DETERMINATION OF AGGREGATE CRUSHING VALUE

2017-5-29  The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS

CORRELATION BETWEEN AGGREGATE CRUSHING VALUE

2016-12-15  Aggregate Crushing Value (ACV) is one of the important properties of coarse aggregate. ACV gives a relative measure of resistance to crushing under gradually applied compressive load. Thus ACV is inversely related to strength of coarse aggregate. In concrete pavement design ACV of coarse aggregate is given much importance.
