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. It is supported on level and plane concrete floor of minimum 45 cm thickness.
The percentage mass of fines (passing a 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 their crushing values.

Aggregate crushing value of aggregates with cement . BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive method is applicable to aggregates passing a mm test sieve and retained on a mm test sieve.
Procedure of Aggregate Crushing Value. Take a sample of aggregates by sieving through and retained on 10mm. The aggregate shall be tested in dry surface conditions. If dried by heating, the period of drying shall not exceed 4 hours and temp shall be 100110 deg C.

BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive method is applicable to aggregates passing a mm test sieve and retained on a mm test sieve.
· Aggregate Crushing test (IS 2386(Part 4):1963 BS 812–110:1990) Aggregate crushing test values indies the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads.
Then crushed aggregates are then sieved through mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.
· The crushed aggregate is allowed to pass through mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.
· Smaller is the aggregate impact value, tougher is the material. This is because the fraction that passes through sieve is actually the crushed material that otherwise was a part of aggregate particle/s. More is the fraction finer than this sieve; less tough the material is.
100 W2 Where, W1 = Total weight of dry sample. Aggregate crushing value = W1 W2 = Weight of the portion of crushed material passing IS sieve. Results: The mean of the crushing value obtained in the two tests is reported as the aggregate crushing value. Limits: The aggregate crushing value for cement concrete pavement shall not exceed 30%.
Conformity Criteria as per BS EN 2061; Rate of Sampling of Concrete. The rate of the sampling depends on the quantity of the concrete to be poured in a particular concrete. For smaller concrete, the sampling rate is higher compared with large volume concrete. The following table extracted from BS 5328: Part 1 indies the rates to be ...
