AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
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. Aggregates crushing value is the resistance of an aggregate to gradually / continuously applied load.
May 01, 2003 percent crushing referred to in that specification is not the same as Sections 1214.6, 1214.7 or 1214.8. Differences are as follows 1. Percent crushing can be determined by samples taken from stockpiles prior to crushing. This is primarily a field test however, should a laboratory receive an uncrushed sample for
The strength of coarse aggregates is assessed by aggregate crushing test. 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, aggregate possessing low
Apr 26, 2018 The determination of aggregate crushing strength is an important test in your civil engineering lab.You know that aggregates are the one the basic unit of building materials.Aggregates are used in several construction processes such as in concrete, road construction etc..
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS

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)
Sep 12, 2015 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.

Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.

Consists of M.S. Cylindrical Container 150mm / 0.5mm dia. x 130mm to 140mm high with base plate 200 to 230mm/sqr x 6mm thick.
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 is subjected to a specified load under standard conditions. Aggregates with lower crushing value ...
The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure of Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110 C for a period of 4 hours and cooled.
