Oct 03, 2019 Sampling for Aggregate Crushing Value Test For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 C to 110 C then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.
Feb 25, 2012 The strength of coarse aggregates is assessed by aggregates crushing test. The crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.
This Part of BS 812 describes methods for the determination of the aggregate impact value AIV which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Two procedures are described, one in which the aggregate is tested in a dry condition, and the other in a soaked condition. The methods

The percentage mass of fines passing a 2.80mm BS test sieve formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than ...
According to BS 812 PART 1121990 standard, the aggregate impact value is related to the crushing value. The tests to determine the values are prescribed in the standard. In aggregate crushing value test, the aggregate is subjected to 400 KN compression load in a cylindrical mold. The crushing value is defined by the percentage loss in mass on ...

3.4.10 Aggregate Impact Value. The impact test BS 812-112, 1990 , as in the case of the compaction test BS 812-110, 1990, has been taken out of the set of standard tests used for determining the physical properties of aggregates for assessing their suitability for use in construction applications.
Dec 19, 2019 If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
