The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load. From the calculations done we know that the aggregate can be acceptable as their Aggregate Impact value is less then 20 Aggregate Impact Value 10.
Aggregate Impact Value Test. 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.
Aggregate Impact Value Civil Engineering. AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse aggregates as per IS 2386 Part IV 1963.
aggregate tests Specific tests used to determine the suitability of aggregates for special purposes. There are tests for a shape and texture the angularity number, to determine whether particles have a large angle of friction with good bonding properties b size and grading, to determine whether particles will pack well c moisture content, to discover whether materials absorb so much

The aggregate should therefore have sufficient toughness to resist their disintegration due to impact. This characteristic is measured by Impact Value Test. The aggregate impact value is the measure of resistance to sudden impact of shock, which may differ from its resistance to gradually applied compressive load. Equipments
AIV Aggregate Impact Value. Looking for abbreviations of AIV It is Aggregate Impact Value. Aggregate Impact Value listed as AIV. Each characteristic of coarse aggregate like specific gravity, bulk density, aggregate impact value and aggregate crushing value has certain influence on ultimate strength of concrete.
Aggregate impact value test gives an indication of aggregates toughness property i.e. property of a material to resist impact Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value Toughness Properties lt10 Exceptionally tough Strong 10 20 Very tough Strong
The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight. Procedure The test specimen includes the aggregates of size ranging from 10.0 mm 12.5 mm. Aggregates can be dehydrated by warming them at temperatue of 100110 C for a
5.1 Impact Value, as determined using the standard 4.5 kg 10 lbm hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates, stabilized soil and recreational turf. Impact Value is one of the properties used to evaluate
Aggregate Impact Value is an ability or toughness of aggregates which 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 Aggregate .
Aggregates Impact Test Conforming to IS 2386 Part 41963 With respect to concrete aggregates toughness is also consider. The resistance of the material to failure by impact is known as toughness. The aggregates should therefore have suffic
Assuming That You Are Refering to Crushing And Impact Tests of Aggregates Crushing Test Gives Us Idea About Strength of Aggregate. Strength Resistance To Gradual Loading Impact Test Gives Us Idea About Toughness Of Aggregate. Tough
Experiment No. 4 Determination of the aggregate impact value of different coarse aggregate samples. BS 812 Scope amp 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 100110 C for a period of 4 hours and cooled.
The percentage mass of fines passing a 2.80mm BS test sieve formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than
