Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2 W1) x 100. Lab Report.

Aggregate suitable for use as pipe bedding would display a low compaction fraction, indicating it reaches a state of near full compaction under loose placement. Test Method Crushing Value The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.
Jul 02, 2021 The aggregate crushing value then calculated by dividing the weight passing on 2.36mm sieve with the whole sample weight in cylinder taken for test . Datasheet for aggregate crushing value Published July 2, 2021 By tsquarecivilengineering.
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred.
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 IS 2386 (Part 4) 1963).
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 . If it is than 30 then 10 finer aggregate is suggested to use. The aggregate whose crushing value is less than 30 can be used for.
Crushing Machine, Tamping Rod, Trowel, Weighing Balance, Cylindrical Mould, Plunger etc. Description Aggregates crushing value The aggregates crushing value is the ability of an aggregate to resist crushing under a gradually applied compressive load. Impact value is the resistance of an aggregate to sudden or impact load.
Jul 18, 2021 Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.
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 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.
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.
