The test is applicable to both weak and strong aggregate. The test is very similar to the aggregate crushing test when a 400 kN force is used and ne aggregates are expressed as a percentage of the original mass. In the ten percent nes value test the aim is to look for the force required to produce 10 % of ne values.

the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, there is another recommended method.
This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.
Sep 12, 2015 Crushing Test Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied ...
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
Feb 08, 2012 The aggregate impact value (AIV) is B AIV 100 (%) . . . (1) ARESULTSAn average is taken of the two tests and the result is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose. For weak aggregates, the required load ...
Aggregate Test. Coarse Aggregate play an important role in construction. Aggregate is one of main constituent of concrete which is widely used in building construction. There are different aggregate test available to check propeties and quality of any aggregate sample.

Aggregate Water Absorption Test. Water absorption gives an idea of strength of aggregate. Aggregates having more water absorption are more porous in nature and are generally considered unsuitable unless they are found to be acceptable based on strength, impact and hardness tests. Water absorption shall not be more than 2% per unit by weight.
