Apr 08, 2017 Objective For the assessment of the aggregate crushing value of coarse aggregate. The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of [ ].Aggregate Crushing Value (ACV) can be determined by using a simple formula This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember 1.It is recommended that the crushing value of.
The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low.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.
Aggregate Crushing Value Test – Determine Aggregate 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 construction is expressed by numerical index .Coarse aggregates, the variation of aggregate crushing value of different coarse aggregates, strength gain of concrete with time for different coarse aggregates and to establish a relation between aggregate crushing value of coarse aggregate and compressive strength of concrete. In the study, Portland Composite Cement (PCC) has not been used.
