Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – per is code it should not be more than 25% for wearing surfaces 45% for non wearing surfaces.
Name of the experiment: Aggregate Crushing value test. Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The "aggregate crushing value" give a relative measure of the resistance of an aggregate to crushing under gradually applied ...
discussion for aggregate crushing value test, conclusion aggregate impact value test aggregate processing plant. aggregate Crushing value test is for determining the aggregate crushing value of coarse aggregates. Go to Product Center. what is conclusion experiment aggregate, impact value experiment for aggregate ?
The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is ...
01/07/2019 · Procedure of Aggregate Impact value test The test sample: normally aggregates sized mm to mm. the aggregates should be dried by heating at 100110 0C for a period of 4 hours and cooled. Sieve the material through and mm IS sieves.
Testing On Aggregate Crushing Value Test 2171 Words ...

Aggregate Crushing Value Seperti Layang Layang Feb 03 2012 so we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load the aggregate are mild tough to have the resistance pressure under ...
Aggregate Crushing Value Civil EngineeringProcedure to determine Aggregate Crushing Value. i) The aggregates passing through and retained on 10mm IS Sieve are oven .Aggregate Crushing aggregate crushing value test procedure
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird 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.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes –, 10mm and Procedure to determine Aggregate Crushing Value i) The aggregates passing through [.]
Aggregate Crushing Value Test Conclusion. Aggregate Crushing Value Test Conclusion. 322012 from the experiment, we get average percent wear are 22 still not exceeding jkrs standard, 30 so we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied.
Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
26/04/2018 · Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (WaWe) W2= Weigh of aggregates passing through IS sieve.
