Coarse aggregates the variation of aggregate crushing value of different coarse aggregates strength gain of concrete with time for different coarse aggregates and to establish a relation between aggregate crushing value of coarse aggregate and compressive strength of concrete in the study portland composite cement pcc has not been used

This test method sets out the procedure for the determination of the aggregate crushing value which is the percentage of fines produced when an aggregate is subjected to a gradually applied crushing force the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing

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

Jul 16 2014 aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates it has been found that for majority of aggregates the aggregate crushing value and aggregate impact

The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads impact value the aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact the impact value of an aggregate is sometime used as an alternative to its crushing value

Sep 12 2015 the aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load the test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions see fig1 dry aggregates passing through 125 mm sieves and retained 10 mm sieves are filled
