The impact value test on coarse aggregate is key in checking material quality for construction It helps engineers and construction experts make better choices This ensures projects last longer and are safer This test shows which aggregates are top notch and which are not Regular testing helps construction managers keep their projects safe
The Aggregate Impact Value AIV test outlined in IS 2386 Part IV evaluates the impact resistance of aggregates This is performed with an impact testing apparatus using a specific procedure and sample preparation method Aggregates acceptable for wearing surfaces in concrete should not exceed a 45% impact value and for bituminous concrete 30%
Sieve analysis specific gravity moisture content Aggregate Crushing Value ACV and Aggregate Impact Value AIV of the granites were determined The aggregates were used to produce concrete of
In the Aggregate impact value test a small portion of coarse aggregates having a size range between 10 to mm is confined in a 75 mm diameter cylindrical metal measure and subjected to 15
Aggregate Impact Value on Coarse Aggregates Apparatus for Aggregate Impact Test The apparatus as per IS 2386 Part IV 1963 consists of i A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter
The quality of construction works in Civil Engineering largely depends on the properties of materials The properties of rock aggregates depend upon the natural conditions of different rock types It has been understood that the changes of engineering properties in different rock types may be related to the rock texture Therefore studies on the engineering properties
The impact of aggregate value offers a relative resistance of aggregate measure to impact or sudden shock Investigation of concrete properties using recycled waste concrete aggregate
Aggregate Impact Value = B/A X 100 where A = weight in g of saturated surface dry sample B = weight in g of fraction passing through mm IS Sieve 6 Reporting of Results The mean of the two results shall be reported to the nearest whole number as the aggregate impact value of the tested material
