The aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load. The property of a material to resist impact is known as toughness.
01-07-2019· Procedure of Aggregate Impact value test The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves.
30-03-2021· Impact test on aggregate is determines the ability of an aggregate to withstand sudden loads. Aggregates are the significant factor that contributes adequate strength to concrete. Therefore it is important to obtain the right quality aggregate for construction. Aggregates are often subjected to impact due to the movement of vehicles on road.
The effects of aggregate type, size, and content on the behavior of normal and, strength of high-strength concrete containing limestone is not affected by aggregate content Flexure test results show that high-strength concrete containing basalt yields, It is well recognized that coarse aggregate plays an important role in concrete.
Application Of Aggregate Impact Value Test. Aggregate impact value test dorry abrasion testing m one of the major factors contributing to the quality of concrete is the quality of aggregates used therein with the wide range of aggregates available it is essential to select an aggregate that is suitable for a given application.
