One of the requirements, for the suitability of aggregates for construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the.
Falls in the range of 7.5 to 12.5 but if it does not fall in this range, the test is repeated with necessary adjustment of the load. Two tests are carried out at the load (x tonnes) which give the percentage fines between 7.5 and 12.5 and aggregate crushing value indicates strong aggregates, as the crushed fraction is low. ~hus the test.

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of.
Mar 10, 2019 The crushing value test of aggregate 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 a 10 mm sieve.The aggregate sample is filled in a cylindrical mold and a load of 40 tons is applied through a plunger in a compression testing machine.
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.

Tional stone crushing equipment can be used, and new crushed aggregate requires slightly higher values. Fine aggregate content is usually 35 to 45 by mass or volume of the total aggregate content. The range of particle sizes in aggregate is illustrated in Fig. 5 4. The aggregate.
Preparation of Aggregate Impact Value Test . The aggregate which uses for the sample is passed through the 12.5mm IS sieve and retain on the 10mm IS sieve. The aggregate which is retained on the 10mm sieve is dried in an oven for a time period of 4 hours at the oven temperature of 100 to 110 C.
Aggregate suitable for use as pipe bedding would display a low compaction fraction, indicating it reaches a state of near full compaction under loose placement. Test Method Crushing Value The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.

If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
