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 = (W2/W1) x 100 Lab Report SI: DescriptionCalculate Aggregate Crushing Value The 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 = W B W A × 100 Where, W A is weight of surfacedry sampleAggregate Crushing Value Calculator, Test on course andThe 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 The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) ADETERMINATION OF AGGREGATE CRUSHING VALUE
