Aggregates

Unitweight measures the volume that graded aggregate and the voids between them will occupy in concrete. The void content between particles affects the amount of cement paste required for the mix. Angular aggregates increase the void content. Larger sizes of wellgraded aggregate and improved grading decrease the void content.
