aggregate crushing value result interpretation

“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations when aggregate value 30 or higher the result may be a mistake and in such cases the “ten percent fines value” should be determined and used instead

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

interpretation of aggregate crushing value The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the 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

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 ACV of an aggregate is the mass of material expressed as a percentage of the test sample which is crushed finer than a 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 21 An
