ReaffirmedDec 2016 test sample shall consist of aggregate the whole of which passes a mm IS Sieve and is retained on a 10 mm IS Sieve. The aggregate comprising the test ...

 · This test is done to determine the aggregate impact value of coarse aggregates. Many tests have been developed toempirically characterize aggregate properties without, necessarily, strong relationships to the performance of final products incorporating an aggregate. This seems to be particularly true for aggregate "toughness and abrasion resistance" and "durability and soundness." .

Aggregate Impact value Test Apparatus, Procedure . Procedure of Aggregate Impact value test The test sample: normally aggregates sized mm to mm. the aggregates should be dried by heating at 100110 0C for a period of 4 hours and cooled.

Procedure of Aggregate Impact Test The test sample consists of aggregates sized mm mm. Aggregates may be dried by heating at 100110° C for a period of 4 hours and cooled. (i) Sieve the material through mm and IS sieves. The aggregates passing through sieve and retained on sieve comprises the test material. (ii) Pour the aggregates to fill about just 1/3 rd ...

Aggregates Impact Value gives relative measure of resistance of aggregates to sudden shock or impact, which in some aggregates differs from its resistance to slow compression load. Impact Value should not be less than 45% for aggregates used for concrete other than wearing surface and 30% for concrete used in wearing surface. Table below shows the classifiion of aggregate with respect to ...

Introduction: The appliion of load on the aggregates such as pavements result into the disintegration of the particles which may result into the loss of strength due to lack of interlocking ability and sudden shock. The load results into the decrease in the compressive strength of the ...
