Relationship Between Aggregate Crushing

Aggregate Crushing Value Test Significance Test The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the is sieve 236mm 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 Abstract Of Aggregate Crushing Value The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load 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 aggregat Relationship Between Aggregate Crushing Abstract this paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value acv and ten percent fines aggregate crushing value tfv for some aggregates in nigeria such a mathematical relationship usually
