The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions Figure 1. Dry aggregates passing through 12.5 mm sieves and retained 10 mm sieves are filled .

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.
The apparatus of the aggregate crushing value test as per IS 2386 Part IV 1963 consists of 1 A 15cm diameter open ended steel cylinder with plunger and base plate of the general form and dimensions as shown in Fig 1. 2 A straight metal tamping rod
percentage of the original weight of the test sample. This value is reported as the percentage of wear. Aggregate Abrassion Value A-BA X 100 where A weight in gm of oven-dried sample. B weight in gm of fraction retained on 1.70 mm IS Sieves after washing and oven-dried upto constant weight. 6.Video Los Angeles Abrasion Test
The aggregate crushing value is a value which indicates the ability of an aggregate to resist crushing. The lower a figure the stronger the aggregates that is the greater its ability to resist crushing. 2.1 THEORY Granular base layers and surfacing are subjected to repeated loadings from truck tires and the stress at the contact points of .
2. To study the various properties of selected material like specific gravity water absorption crushing value impact value and gradation to determine the suitability for high strength concrete. 3. Mix Design of M30 grade cement concrete based on IS code and IRC 44-2008. 4. Check for compressive strength as well as flexural strength. 5.
The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13295mm aggregate so that 10 per cent of the total test sample will pass a 2 36 mm sieve. 2 APPARATUS As in SABS Method 842. 3 METHOD Follow SABS Method 842. 4 CALCULATIONS

One of the requirements for the suitability of aggregates for construction is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the
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 2.36 mm size of test. Bigger percentage of aggregate crushing value means the aggregate is inferior in quality. According to BS 8821992 aggregate with crushing value less
The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13295mm aggregate so that 10 per cent of the total test sample will pass a 2 36 mm sieve. 2 APPARATUS As in SABS Method 842. 3 METHOD Follow SABS Method 842. 4 CALCULATIONS

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 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An .
Oct 03 2019 The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations when the aggregate value 30 or higher the result may be a mistake and in such cases the ten percent fines value should be
NOTE 1 -The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate 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. .
These two aggregate samples were tested for sieve analysis test relative density test water absorption test ten percent fine test aggregate crushing value test ACV Aggregate impact value test AIV and Abrasion value test. Findings revealed that the best aggregate for road construction is the aggregate
the aggregate crushing value ACV which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions there is another recommended method.
Mechanical Properties of Aggregates Aggregate Crushing Value Test Discussion There is no explicit relation between the aggregate crushing value and its compressive strength but in general the crushing value is greater for a lower compressive strength. BS 812 Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete.
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 2.36 mm size of test. Bigger percentage of aggregate crushing value means the aggregate is inferior in quality. According to BS 8821992 aggregate with crushing value less

May 17 2019 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load
