Aggregate Impact Value Test Impact Test Of Aggregate

Importance of Impact Test on Aggregates The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or Procedure of Aggregate Impact Test The test sample consists of aggregates sized 100 mm 125 mm Aggregates may be dried by heating at 100110° C for a period of 4 hours and cooled (i) Sieve the material through 125 mm and 100mm IS sieves The aggregates passing through 125mm sieve and retained on 100mm sieve comprises the test materialDetermination of Aggregate Impact Value Impact Test Various Test on Aggregate The following are the aggregate testing methods, 1 Impact Test on Aggregates What Is Impact Value Of Aggregate? It is the ability of aggregates that resist sudden impact or shock load on it Also, it can be defined as the resistance of aggregate to failure by impact load is known as the Impact Value of AggregateAggregate Testing 7 Test On Aggregates Coarse
