Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive load.Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve.
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.
The aggregate crushing value acv test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.All parts of the apparatus are powder coated or galvanized steel, heat treated and ground.
Aggregate crushing value w b w a 100 record.The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material.Safety precautions use hand gloves while removing containers from oven after switching off the oven.To wear safety shoes helmet during the time of test.
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.Crushing value is a measure of the strength of the aggregate.The aggregates should therefore have minimum crushing value.
As per is 383 this apparatus is used to measures resistance of an aggregate to crushing under a gradually applied compressive load.Specification consists of m.Cylindrical container 150 mm 0.5mm dia x 130mm to 140mm high with base plate 200 to 230 mm.A plinger of 148mm 0.5mm dia x 100 to 115mm high.
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value.In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the aggregate crushing value.A data sheet is given as form 7.
An aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger.The specimen is then loaded via the plunger.The load crushes the aggregate to an extent depending on the crushing resistance of the material.It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value acv.
