Aug 30 2017 Principle of the Test To produce the abrasive action by use of standard steel balls which when mixed with the aggregate and rotated in a drum for specific number of revolution cause impact on aggregate. The age wear due to rubbing with steel balls is determined and is known as abrasion value. Prepare the sample by the portion of an aggregate .
This test helps in determining the value which indicates the ability of an aggregate to resist crushing. The lower the figure the stronger the aggregate i.e. the greater its ability to resist crushing. Test Method IS 2386 P-4 1963 ASTMC 131-2006. Lightweight Pieces
Feb 01 1991 The reduction he suggests in the value of K from 4000 to 2800 is based upon samples of crushed rock aggregates i.e. all the samples were obtained from aggregates produced by crushing various types of hard rock. I and other workers have found that the previous value of K 4000 works quite well when testing aggregate from sand and gravel sources.
3.8. Aggregate Crushing Value ACV of the Coarse Aggregate. This test was carried out following British Standard 16. The sample was filled into the mould in three layers and given 25 tamping at each layer. The weight was measured as A. The apparatus was then placed in the compression testing machine and loaded at a uniform rate to achieve a .

DETERMINATION OF AGGREGATE CRUSHING VALUE 2.1 Object - This method of test covers the procedure for determining aggregate crushing value of coarse aggregate. NOTE 1 -The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of aggregate crushing value 30 or higher the result may be anomalous and in such cases the ten percent fines value should be determined
