## Method B1 The Determination Of The Aggregate

Determination Of Aggregate Crushing Value 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 the apparatus of the aggregate crushing value test Aggregate Crushing Value ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place aggregate crushing value ba x 100 where a weight of ovendried sample b weight in g of fraction passing through 236 mm is sieve aggregate crushing value test Aggregate Crushing Value Test Step By Step Procedure 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 it is recommended that the crushing value of aggregate should be less than 30 Aggregate Crushing Value Test Significance Test Calculation of aggregate crushing value 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 the crushing value of aggregate
