Welcome to our Facmaster Factory!
this characteristic is measured by impact value test. the aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. apparatus the apparatus of the aggregate impact value test the aggregate impact value testing apparatus, meets with BS 812, it is robustly designed to determine the aggregate impact value of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. the counter fitted to the machine automatically records the number of blows delivered to the sample mar 11, 2013 aggregate impact test, ten percent fines test and aggregate aggregate impact test, ten percent fines test and aggregate crushing test. report the applied force, the masses of material before and after sieving, more detailedthe 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 imes freely. after filling the sample aggregate, weigh and record it as now fill the aggregate in the mould along with the plunger on top.feb 08, 2012 impact, 10% fines & crushing testsfigure apparatus for the 10% fines test and aggregate crushing test the material used for both tests is aggregate passing a 12.70 mm sieve and retained on a 9.52 mm sieve.
