Concrete Aggregates
Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate. Concrete Aggregates are produced to Australian Standards (AS 2758) or to more specific customer requirements.

New grading requirements are introduced for coarse aggregates containing 2 mm to 10 mm fractions with the inclusion of limits for material passing a 14 mm sieve. This ensures a reasonable fraction of the aggregate will be retained between the 20 mm and 14 mm sieves and eliminates the anomaly that some nominal 14 mm aggregates previously ...

Gleason grading
Aug 20, 2021 · Gleason grades 1 and 2 are discontinued. Grading is not recommended for perineural invasion because perineural invasion distorts gland morphology (grade 3 looks like 4). For tumor that is 1 mm or less, only 1 grade needs to be assigned, avoiding doubling Gleason 4 to 4+4=8, which would be misleading if cancer in other cores is mostly Gleason 3.
