Importance Of Aggregate Grading

Importance of aggregate grading. Ideally coarse and fine aggregate should be graded in such a way as to minimise the voidage. After compaction the volume of the cement paste must be more than the voidage between particles. Underfilling will result in entrapped air and an unworkable mix. An extreme example of this is a no-fines concrete where .
