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

Preparation of Aggregate Impact Value Test:- The aggregate which uses for the sample is passed through the 12.5mm IS sieve and retain on the 10mm IS sieve. The aggregate which is retained on the 10mm sieve is dried in an oven for a time period

Experiment Name: Determine of Aggregate Impact Value Test: BS 812 Purpose of the test: The Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition.

Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.

Aggregate impact value test Machine Take a sample of aggregate and sieve with the help of a 12.5-millimeter sieve and retain it into a 10-millimeter sieve. Sieving should be done in a circular motion. After that sample should be sieved with 10 millimeters sieve and collect in a container.

Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.

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. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

The aggregates are classified on the basis of their impact value as From the above classification, the given aggregate samples can be classified as Strong Aggregates because their respective impact values are in the range 10 to 20% Rate this (1 Vote)

Precaution for aggregate impact value test The sample of aggregate should be sieved in circular motion or movement. The sample aggregate should not be overheated on the oven. The weight of samples and dust should be tamped with the help of a standard size tamping rod. The hole of sieve should not be ...

The Impact value of an aggregate is the percentage loss of weight particles passing 2.36mm sieve by the application of load by means of 15 blows of standard hammer and drop, under specified test condition.

Sample Experiment Aggregate Impact Value. Experiment mechanical testing- impact hardness testing objective.Sample standard deviation can be computed as the following table presents the data in rank order, the mean deviations di and the ratio of the mean.The mean value of the revised data set, without the chauvenet rejected data points included, should.

Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling a set height, a prescribed number of times, onto an amount of aggregate of standard size and weight retained in a mould.

14-07-2018 AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load. The Indian Standard CODE IS 2386 (Part IV) – 1963 is used for procedure and classification of aggregate by result.
