Jan 25, 2021 Aggregate Crushing Value (ACV) IS 2386 2016 Method of Test for Aggregates for Concrete part IV Mechanical properties (Aggregate Crushing value) (The ‘aggregate crushing value’ gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.Aggregate Crushing Value and Its Test Procedure One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS 2386 part IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on.
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.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.
Aggregate crushing value test discussion. 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 under standardized conditions.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.

Toachieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.Apparatus The apparatus for the standard aggregate crushing test consists of the following (i) Steel cylinder with open ends, and internal diameter 25.2 cm, square base plate plunger having a piston of diameter ~ with a hole provided.Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step loading compression tests were conducted on the mixtures of PA 13 and a control asphalt mixture AC 13, respectively.
The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load.Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.The aggregate sample is filled in a cylindrical mold and a load of 40 tons is applied through a plunger in a compression testing machine.Briefly explain the aggregate crushing value test procedure.
