  • Aggregate Sizing Explained Chaney Enterprises

    Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve. This is then broken down into four types of grading Zones 1 through Zone 4 with Zone 4 being the most fine.

  • On Aggregate Grading

    On Aggregate Grading is good concrete performance dependent on meeting grading limits? Specifying concrete mixtures with well-graded (WG) combined aggregates can be controversial. Advocates1-4 argue that such mixtures have optimized packing and minimal voids and therefore minimize the cementitious paste required for a given workability.
