Suitable mass of material to determine the Aggregate Crushing Value. Grade of the aggregate Minimum mass of test portion All-in aggregate 40 mm max. size All-in aggregate 20 mm max. size Graded aggregate 40 to 5 mm Graded aggregate 20 to 5 mm Graded aggregate 14 to 5 mm 60 kg 45 kg 40 kg 25 kg 15 kg 7.7.1.7 Procedure.
Aggregate crushing test is standardized by IS 2386 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on 10mm sieve. The cylindrical steel cup is stuffed in three layers of aggregate. Each and every layer is tamped with 25 strokes by the rounded end.
Aggregate Crushing Value Test Determine Aggregate 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 .
Aggregate Crushing Value Test. 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.
Mar 20, 2019018332When the mortar was completely removed, coarse natural aggregates were obtained. The attached mortar contents of the RCA and the C-RCA in the test were derived as follows 6 Attached mortar content M 0-M n M 0 215 100 where M n is the mass of coarse natural aggregates in RCA and C-RCA samples after the crushing stress test was performed.

Moreover, the coarse aggregates will easily blend with other concrete ingredients and make it as a homogeneous element. The impact value test has been conducted on aggregate to determine its bearing capacity against sudden impact. Here we are going to discuss the crushing value of aggregates. What is an aggregate crushing value.
7. Effect of Pressure on the Crushing Value of Coarse Aggregate. The greater the pressure on aggregate, the easier it will be crushed. When the crushing test of coarse aggregates is carried out, the contact stress between coarse aggregates should be consistent with the actual contact stress between coarse aggregates in actual pavement.
Aug 26, 2020018332The test evaluates the ability of the Aggregates used in road construction to withstand the stresses induced by moving vehicles in the form of crushing. With this the aggregates should also provide sufficient resistance to crushing under the roller during construction and under rigid tyre rims of heavily loaded animal drawn vehicles.
