Crushing value test of aggregate in sweden

1.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 = (B/A) X 100 where A = weight of oven-dried sample B = weight in 'g' of fraction passing through 2.36 mm IS sieve. 6.Video Aggregate Crushing Value Test
