Aim:- To Determine Aggregate Crushing Value Scope:This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. Apparatus:Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a ...

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm

Aggregate Impact Value on Coarse Aggregates Apparatus for Aggregate Impact Test. The apparatus as per IS: 2386 (Part IV) – 1963 consists of: (i) A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter.

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.

So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate are mild tough to have the resistance pressure under traffic wheel loads such as car, lorry, motorcycle and etc.

It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value (ACV). A compression testing machine of 500/600 kN capacity, a suitable steel cylinder and plunger are required to perform this type of test (see links below).

Aggregate crushing Value =(WB/WA) × 100 Record The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. to the first decimal place. o After test electric supply should be off.

aggregate crushing value (ACV), aggregate impact value (AIV) and 10 percent ﬁnes ag- gregate crushing test (10 % FACT)) with quantitative analysis (mineral grain size and mineral grain size distribution), it is possible to determine the mineral grain size corre-

Sigmatest Uses The Best Equipments For Tests Like Aggregate Testing, Aggregate Impact And Crushing Value Test, Flakiness Index And Petrographic Analysis In The Laboratory To Find The Strength, 10% Fine Value: All aggregate is required to meet a .

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.

For determination of the aggregate crushing value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Reference Standard IS: 2386 (Part IV)-1963 Methods of test for aggregate for concrete Part IV Mechanical Properties.

AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm
