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 the sand fraction is minimised, the course aggregate,The importance of aggregate gradation for concrete,19/01/2016· The importance of aggregate gradation for concrete quality. Choosing the proper aggregate gradation when it comes to mixing up the right potion of concrete could mean make or break, literally, when constructing any type of building or structure.
