MENÜ
A flakiness test is done to find the thickness of the aggregate i.e., the least lateral dimension. The thickness of the aggregate or least lateral dimension should not be less than 0.6 times the mean size of the aggregate i.e., 0.6(x+y/2), where, x smaller size of the aggregate in the sample, y is the larger size of the aggregate.

Nov 07, 2022· Therefore, an aggregate crushing test is conducted to ascertain the aggregate's structural soundness and crushing strength. The aggregate crushing value gives a comparative indication of the resistance to crushing under a crushing load that is applied gradually. The recommended value of a crushing test should ideally be 30% for …

Dec 05, 2021· There are a variety of tests that can be performed on aggregate. One of the1 main tests is known as the sieve analysis. This test determines what size pieces are in the aggregate, and how evenly they are distributed. To perform this test, an aggregate sample is poured through a series of screens that have different sized holes in them.

Aug 25, 2022· The conventional aggregate crushing value test (ACVT) applies a load of 400 kN, which results in a compressive stress of 22.65 MPa. This stress level is believed to be far higher than those to which coarse aggregates are subjected under actual compaction and traffic loads. The static load of ACVT may not well reflect the crushing behavior of ...

After each layer, tamp 25 times for good compaction. Then take the weight of the cylinder with aggregate. Place the apparatus, with the test sample and plunger in position on the compression testing machine. Apply the compressive load of 40 tons in 10 mins. Then remove the specimen from machine and sieve the aggregates through 2.36 mm.
