“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations when aggregate value 30 or higher the result may be a mistake and in such cases the “ten percent fines value” should be determined and used instead
The determination of aggregate crushing strength is an important test in your civil engineering know that aggregates are the one the basic unit of building ates are used in several construction processes such as in concrete road construction etc Aggregate crushing value W2
