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
The method is applicable to aggregates passing a 140 mm test sieve and retained on a 100 mm test sieve an aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger the specimen is then loaded via the plunger the load crushes the aggregate to an extent depending on the crushing resistance of the material
Number report the mean as the aggregate crushing value unless the individual results differ by more than 007 times the mean value in this case repeat the test on two further specimens calculate the median of the four results to the nearest whole number and report the median as the aggregate crushing value a data sheet is given as form 771
Procedure for crushing strength of aggregate before testing the aggregate should be in surface dry can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100degree celcius the aggregates passing through 125mm and retained on 10mm is sieves are selected for finding aggregate crushing strength
