The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 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 aggregates.
Maximum size of coarse aggregate: Maximum size of aggregate affects the workability and strength of CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963.
Results: The mean of the crushing value obtained in the two tests is reported as the aggregate crushing value. Limits : The aggregate crushing value for cement concrete pavement shall not exceed 30%. The aggregate crushing value for wearing surfaces shall not exceed 45%.

Apr 25, 2019· Ans. 10 % fines value of an aggregate is the resistance strength of crushing. What is the IS code used for 10 percent fines value test procedure? Ans. IS 2386 part 4 is used for 10 % fines value test procedure.
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, and the strength of the aggregate used in road .

To obtain high strength concrete, coarse aggregate size is usually held to a maximum size of 19 mm, but additional cement is required for the additional surface area. The fine aggregate can generally contain less material passing 300 um and 150 um sieve because of the higher cement content.
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 mm test sieve and retained on a mm test sieve.
Sep 24, 2010· One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 partIV 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.

What Is Crushing Strength Of Concrete What is the Crushing strength of M 25 concrete at seven days.
Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but many ...
