- Aggregate Crushing Value And Aggregate Impact Value

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.
