  • Aggregate Crushing Value Test Step By Step Procedure

    1.It is recommended that the crushing value of aggregate should be less than 30. If it is more than 30 then 10 finer aggregate is suggested to use. 2.The aggregate whose crushing value is less than 30 can be used for cement concrete road. 3.The aggregate whose crushing value is less than 40 can be used for wearing surface. This test must be done before it comes to road and pavement

    Oct 04 2020 The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates as the crushed fraction is low. Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.

    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 under

  • Aggregate Crushing Value Acv Civil Engineering

    The standard aggregate impact test shall be made on aggregate passing a 14.0 mm BS test sieve and retained on a10.0 mm BS test sieve. If required or if the standard size is not available smaller sizes may be tested but owing to the non-homogeneity of aggregates the results are not likely to be the same as those obtained from the standard size. In general the smaller sizes of aggregates will give a lower-impact value but the relationship between the values
