Aggregate Crushing Value Test -Determine Aggregate

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. Procedure to determine Aggregate Crushing Value.

Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load The aggregate crushing value should not exceed 45 for aggregate used for concrete other than for wearing surfaces and 30 for concrete for wearing surfaces such as runways roads for pavements

aggregate crushing value limits for concrete. 1 Crushed tile as an aggregate possesses some qualities of a good aggregate From the results of the study, the aggregate crushing values and aggregate impact values of crushed tiles were 2338% and 2519% which are less than 30% according to standards and it is therefore suitable for concrete ,

Crushing Value 30 45 Impact Value 30 45 Abrasion Value (Los Angeles) 30 50 Limits of Chloride content of Concrete Type or use of concrete Maximum total acid soluble chloride Correction in Coarse Aggregate values The table specified for W/C ratio

16/04/2020· Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

15/02/2019· Aggregate Crushing Value (ACV) Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

Aggregate Crushing Value Limits For Concrete We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.

Aggregate Crushing value test: This test was performed as per IS: 2386 (Part IV) 1963 The crushing value of RCA was 20% It was also less than the upper limit according to IS Code which is 30% Hence the RCA is used as road construction material also Slump Test: The Slump test was also conducted in laboratory according to IS: 1199 1959.

Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV, than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength, will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate

Aggregate crushing = (W2/W1)*100 Value (per cent) Aggregate Crushing Mean Value =
