### Aggregate Crushing Value Test Procedure, Result

Aggregate Crushing Value is the relative resistance of aggregates to crushing under gradually applied compressive load. The aggregate Crushing Value Test is an important test to be performed on aggregate. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Aggregate Crushing Value Test The Constructor

To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred. With aggregate of an aggregate crushing value higher than 30 the result may be anomalous and in such as the ten percent fines value should be determined instead SAMPLING The standard aggregate crushing test shall be made on portions required to obtain a suitable mass of material to determine the aggregate crushing 5.6 A compression testing machine, capable of value applying any force up to 400 kN and which can be operated to give a uniform rate of loading so that Grading of the aggregate Minimum mass of the test portiona this force is reached in 10 min (see 7.2).Testing aggregates Part 110: Methods for determination of aggregate

So this aggregate was not strong. 4 CONCLUSION. The ACV value is more than 45% for aggregate used for concrete for non- wearing surface and less than 25% for wearing surface like runways and roadways. The higher the aggregate crushing value, the lower the resistance to crushing under the gradually applied compressive load. 5 REFERENCESCrushing value is defined as the ratio of finess passing a standard sieve produced by crushing under standard condition to the weight of coarse aggregate expressed as a percentage. Aggregate crushing values as determined by the IS code method shall not exceed 30 for aggregate to be used for making concrete for wearing surface such as Determination of Aggregate Crushing Value PDF Density
