  • How to Determine the Aggregate Crushing Strength Value in

    Apr 26, 2018· The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength. After sieving aggregates, a cylindrical measure is taken and find the empty weight of cylindrical measure(We).It is then filled with aggregates in three layers with 25 blows to each layer using a tamping rod.
