Inquiry OnlineThis percentage is known as a crushing value of aggregate. This percentage should not exceed 30 of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 for the concrete used for roads and pavements and in case of other structures; it may be permitted up to 45.

Aggregate Impact Value W B W A 100. Where W A is Weight of oven-dried sample; W B is Weight of fraction passing through 2.36-mm IS Sieve; 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.
Aggregate impact value is measured of toughness of aggregate . Toughness is the property of material which indicate its capacity which impact in sudden. Tougher the aggregate more suitable for wearing surface such as road surface. Lower the impact value stronger the aggregate again the impact these for good quality concrete aggregate with ...

Ian Sims Bev Brown in Lea's Chemistry of Cement and Concrete Fourth Edition 1998. Aggregate impact value. A small portion of 14–10 mm sized coarse aggregate particles is confined in a steel pot and subjected to 15 blows by a small hammer in a standardised test rig after which the ‘ aggregate impact value’ AIV is determined from the fine material generated expressed as a ...
In the Magazine of Concrete Research of 1999:291-304; this work reported the applicability of the BS approach to a range of 13 different aggregate types from a source in South Africa that the strength of concrete depends not only on stiffness particle sizes shape and texture mix design but on selected sources of the aggregates.
Jul 16 2014 Aggregate impact value test gives an indication of aggregate’s 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 10 Exceptionally tough Strong 10 – 20 Very tough Strong
May 27 2020 Therefore aggregate Impact value BA100. Where B It is termed as the weight of fraction passing 2.36 mm IS sieve . A It is termed as the weight of the Oven-dried sample. Conclusion. It is noted that the aggregate impact value should not be greater than 45 by its weight.
Place the mould in the aggregate impact testing machine and administer 15 numbers of blows of a metal hammer. After that remove the crushed aggregate and sieve it through a 2.36 mm sieve. The aggregate impact value is measured as of aggregates passing through the 2.36mm sieve W2 to the total weight of the sample W1.
Procedure. Step 1 – First the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 – Now the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.
Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value AIV which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Principle A test specimen is compacted in a
The CBR value of the steel slag aggregates is found to be 21.32 and 25.62 for soaked and unsoaked conditions respectively. • The impact value of steel slag aggregates is found to be 13.90. The aggregate impact value should not exceed 45 by weight of the aggregate
