(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.
Aggregate crushing value test video aggregate crushing value test nptel doskonalykucharz eu Aggregate impact and crushing test Know crushing value of coarse aggregates bs.The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source The Constructor, Civil Engineering Home).Test Method IS 2386 (P-1) 1963. Impact Value This test helps in determining the value which indicates the ability of an aggregate to resist crushing. The lower the figure the stronger the aggregate, i.e. the greater its ability to resist crushing. Test Method IS 2386 (P.

Aggregate Crushing Value Test Anna University . contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results.Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.Mar 20, 2021 Aggregate crushing value gives a relative measure of the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, this test is made on single sized aggregate passing 12.5 mm and retained on 10 mm sieve. The aggregate is placed in a cylindrical mould and a load of 40 ton is applied through a plunger.

According to the results of PFC2D analysis, the contact stress between coarse aggregates in PA-13 mixture is higher than that in AC-13 mixture to reflect the difference of contact stress between coarse.
This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30 .These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration. 150mm Aggregate Crushing Value Apparatus.Aggregate Crushing Value Test.
