Discussion Of Aggregate Crushing Value

Discussion Of Result Of Aggregate Crushing Value aggregate crushing value discussion determine aggregate crushing value test wikipedia Mechanical failure in rocks generally means either fracturing or permanent deformation as a result of compressionAggregate Crushing Value (ACV) can be determined by using a simple formula This test is repeated once or twice and the average crushing value of the aggregate is determined The average crushing value in the different tests is the actual crushing value of aggregate Important points to remember 1 It is recommended that the crushing value ofCalculation 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 = (W2 W1) x 100 Lab Report
