Definition and Classification of Aggregates
The classification of aggregates for concrete according to size is the most common classification, where aggregates are classified as coarse or fine. Coarse aggregates; Coarse aggregates consist of particles that are retained on a sieve with 4.75 millimeters openings (No.4). Generally, the upper size is about 75 millimeters, however …

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.

What Is Coarse Aggregate | Uses and Classification of the Aggregates
Introduction. Coarse aggregate is an essential component of concrete and plays a vital role in the construction industry. It consists of granular materials, such as crushed stone, gravel, or recycled concrete, which are larger in size compared to fine aggregates.

How Coarse Aggregate Affects Mix Design of Concrete?
Smaller maximum size of coarse aggregate would require greater fine aggregate content to coat particles and maintain cohesiveness of concrete mix. So, for the same workability, 40mm down aggregate would have lower water/cement ratio, thus higher strength when compared to 20mm down aggregate.

How size of aggregate affect on strength of concrete?
However, as the hydration reaction proceeds, the second generation hydration gels are produced, making the zone denser but still comparatively weaker than the rest of the concrete. This happens in all sized aggregates. But as the size of the aggregate increases, the surface area of the aggregate also increases. As a result, the …
