  • Aggregate Crushing Value Test Significance & Test

    The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top. Then place the cylinder on the compression

  • How to determine the crushing value of aggregate? Civil

    22/5/2020· The aggregate crushing value= B/A*100 . Where, B is weight of fraction passing 2.36mm sieve ; A is weight of surface dry sample taken in mould. Note. The aggregate crushing value should not be more than 45% for aggregate used for concrete other than the wearing surfaces. 30% for concrete used the surfaces such as runway, roads and air field pavements.

  • Aggregate Crushing Value Test Procedure And Result

    Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve. The aggregate sample is filled in a cylindrical mold and a load of 40 ton is applied through a plunger in a compression testing machine.

  • What is the Crushing value of Aggregates..?? Firstalert

    27/5/2020· aggregate Crushing value=( B/A)*100. Where B is Termed as the weight of fraction passing 2.36 mm IS sieve . A is Termed as the weight of surface dried sample taken in a mold. The aggregate crushing value should not be more than 45% by weight. For aggregates used for concrete other than wearing surfaces and 30% by weight for concrete to be used as wearing surfaces such as runways,

  • Aggregate Crushing Value Test Determine Aggregate

    17/5/2019· The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate

    specimens in the aggregate crushing mould constant when testing any aggregate sample"so that the test, conditions remain unaltered. If the quantity of test sample to be taken is specified by weight, the volume and hence the height may vary depending on the variation in specific gravity and shape factors of different aggregates. When aggregates are not available, crushing strength test may be

  • 7 Lab Tests on Aggregates to Make Better Concrete for

    The crushing mould is filled in three layers with aggregates. Then the weight (W1) of the aggregate in the crushing mould is noted. After that, the mould is placed in the compression testing machine and loaded at gradually applied load so that it reaches a load of 40 tons in 10 minutes. The load is then released and the aggregates are then removed from the mould. Aggregates are then sieved
