purpose purpose of aggregate crushing value

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value

aggregate crushing value test -determine aggregate

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. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements

Feb 08, 2012 · The aggregate impact value (AIV) is B AIV = × 100 (%) . . . (1) ARESULTSAn average is taken of the two tests and the result is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose. For weak aggregates, the required load

Aggregate Crushing Value – Significance & Test Procedure 4 Mins Read The primary purpose of using coarse aggregates is to enhance the strength of the concrete. Moreover, the coarse aggregates will easily blend with other concrete ingredients and make it as a homogeneous element

aggregate crushing value test | step by step procedure

aggregate crushing value test | step by step procedure

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 more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for

new testing methodology for the quantification of rock

Oct 30, 2018 · For this purpose, the mineralogical, physical, and mechanical properties of various hard rocks were determined. A new compressive crushing value (CCV) testing methodology was proposed. The results obtained from CCV tests were compared with those from mineralogical inspections, rock strength as well as mechanical aggregate tests
