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.Aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, with typical range values, are shown in Table 2. number and size of sieves selected for a sieve analysis depends on the particle sizes present in the sample and the grading.

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).Feb 15, 2019 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.

Aggregate Crushing Value Test. This testing method is known as an aggregate crushing value test. Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve.Aug 27, 2019 The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample.

Oct 03, 2019 Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.77 Aggregate Crushing Value and 10 Fines Value 771 , number Report the mean as the Aggregate Crushing Value, unless the individual results differ by than 007 times the mean value In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value A data sheet is given as Form 771.
