Aggregate crushing value and its test procedure one of the test in which concrete material can fail is due to crushing under compressive stress aggregate crushing test is standardized by is 2386 partiv and used to verify the crushing strength of aggregates.
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 45c standard guideline for crushing test followings are the various guidelines.
The aggregate crushing value acv provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive loadwo versions available 150 standard and 75 mm diahe apparatus comprehend cylinder, plunger, base plate.
Procedure to determine aggregate impact value i the cup of the impact testing machine should be fixed firmly in position on the base of the machine and the whole of the test sample placed in it and compacted by 25 strokes of the tamping rod.
Note for strong aggregate, crushing value should be lowor surface courses this value should not exceed more than 30 and for courses not more than 45uestions for discussion which property of aggregates is measured by this test how aggregate.
With aggregate of aggregate impact value higher than 30 the result may be anomalouslso, aggregate sizes larger than 14 mm are not appropriate to the aggregate impact testhe standard aggregate impact test shall be made on aggregate passing a 14mm bs test sieve and retained on a10mm bs test sieve.
