Aggregate crushing value test provides strength of aggregates for resistance against crushing under loads and is used for roads and pavements construction. Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load.
May 27 2020nbsp018332Purpose. The crushing value of an aggregate indicates its resistance against crushing under gradually applied compressive loads. The standard aggregate crushing test is made on aggregate passing 12.5mm IS sieve and retained on 10 mm IS sieve. Procedure. About 6.5 Kg material consisting of aggregates passing 12.5mm IS sieve and retained on 10mm.

Purpose Aggregate Crushing Value Test. 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.
May 08 2013nbsp018332Aggregate crushing Value W B W A 215 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety amp Precautions Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes amp helmet during the time of test.
Aggregate impact value The value of aggregate impact test W1W2100. The value of aggregate impact test should not be more than 45 by weight of aggregates used for concrete other than wearing surface. An impact value 35 is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40.
What is the significance of ten percent fines value in Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate Fine aggregates are defined as those passing 236mm sieve The test aims at looking for the forces required to.purpose of aggregate crushing value testAggregate Crushing Value Test.
The aggregate shall be taken as in the case of crushing strength value test i.e. the aggregate should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. It should be oven dried at 100176C to 110176C for four hours and then air cooled before test.
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.
BS 812 part 110 describes a method to determine the aggregate crushing value ACV which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963. The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes 12.5mm 10mm and 2.
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.
Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing degradation and disintegration. This test is carried out by AASHTO T 96 or ASTM C 131 Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine.

The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a gradually applied compressive load. 7.7.1.2 Scope. The particular purpose which an aggregate is meant to serve requires the aggregate to have a particular strength. This strength is usually stated in the specification.
