The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired. The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate.

A.: Richard Meininger replied that there is no problem designing a concrete mixture with 3/8-inch maximum size coarse aggregate (pea gravel or crushed stone) using the ACI 211 proportioning procedures for a concrete slab placed by pumping. But the concrete will shrink more than a No. 57 mixture, so control joints must be at a closer spacing ...
suitable coarse aggregate as in the conventional concrete. Although, Bida bush gravel has shown a tremendous performance in concrete works, there is very little information on this material in the technology of self compaction concrete. This research therefore is set to explore the potentials of Bida bush gravel in SCC. 2.
The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes contain both angular and round particles. The coarse aggregate particles are usually crushed stone or crushed gravel, and the fine aggregate particles are usually natural sand.
First, there's really no difference in this context between stone and gravel and aggregate. In C 33 there's a chart showing the grading requirements for different sizes of coarse aggregate from #1 to #8. For example, #1 aggregate is nominal size 3½ to l½ inches (90 to 37.5 mm).

AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 µm (No. 200) sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
The term "aggregates" as used in the construction industry is a broad category of coarse and fine particulate material including sand, gravel, crushed stone, slag, recycled concrete, and geosynthetic aggregates and are actually the most mined materials in the world.
Coarse Aggregates All Coarse Aggregates A special requirement placed on all coarse aggregates deals with the restriction on the number of flat and elongated pieces. Section 904.03 sets the limits for the number of flat and elongated pieces. A flat and elongated piece is defined as one having a ratio of length to thickness greater than five.
